John Martin Posted October 2, 2007 Share Posted October 2, 2007 I've head of beeswax and olive oil together 1:1, but is there anything else that I could use that gives it a nice finish??? I haven't tried that yet, because I still have to get some beeswax. But, any thoughts? Quote Link to comment Share on other sites More sharing options...
gerald Posted October 2, 2007 Share Posted October 2, 2007 I use several finishes: Linseed oil, Bee's wax, Johnson's paste wax, plain old parrafin, combination of B. wax, John's PW , & L. oil; but my favorite and most often used is MINWAX wood finishing wax. It goes on well and buffs to a nice deep shine. Quote Link to comment Share on other sites More sharing options...
John Martin Posted October 2, 2007 Author Share Posted October 2, 2007 How do you apply the coating? brush it on and then heat it up or what?? Quote Link to comment Share on other sites More sharing options...
gerald Posted October 2, 2007 Share Posted October 2, 2007 Most finishes of the "wax/oil" variety are brushed onto the item at a heat warm enough to cause the stuff to melt and run into crevices and pores of the metal. The temp isn't critical but can be too hot and actually burn the finish stuff away before it does any coating. If wax smokes, I wait a little while until it melts and flows well without actually smoking. Some finishes (like Linseed oil, parrafin and bee's wax) can burn to a darker finish if applied to hotter metal. This can be used to advantage if you want a darker finish but can be a disadvantage if you want the "natural" patina of the metal to show thru. I use a natural bristle brush (a 1" paint brush, or a chip brush, or a basting brush) because sometimes I try to start brushing stuff on before it has cooled enough to be effective. When this happens, the bristles burn and I don't want to have some melted nylon gunk to clean off of the piece before I can continue. The natural bristles will just shrivel up and will brush off easily. As you experiment with different finishes, you will develop a feel for the proper temp that gives you the desired finish.

Frosty Posted October 2, 2007 Share Posted October 2, 2007 You can reduce the melting temp of waxes by combining them with turpentine. If you soften it to the consistency of a soft paste wax you can wipe it on the piece and heat in the oven for specific and repeatable results. polyrmerizing oils like linseed or olive (to name but two) benefit from the addition of Japan drier available at paint suppliers. Baking polymerizing oils in the oven speeds the process as well and can be used to produce nice colors from golden to black as desired.

John Martin Posted October 2, 2007 Author Share Posted October 2, 2007 So, if I use beeswax and olive oil on let's say a hammer head, and bake it in the oven, i could make a golden dark or a black color?? Quote Link to comment Share on other sites More sharing options...
gerald Posted October 3, 2007 Share Posted October 3, 2007 I might add that all the wax/oil finishes we've talked about are generally thought of as "indoor" finishes. If you have a piece that will live outside, you need to consider some sort of paint/lacquer, etc. Quote Link to comment Share on other sites More sharing options...
John Martin Posted October 3, 2007 Author Share Posted October 3, 2007 Okay, I'll get some black outdoor paint then to. Quote Link to comment Share on other sites More sharing options...
the_sandy_creek_forge Posted November 28, 2007 Share Posted November 28, 2007 To address the original question: "What is the best polish/rust protector/finish" I'd say it all depends on the application. For finish on interior railings, towel bars, knick-nacks, etc. the aforementioned wax finishes seem pretty good and buff up pretty nice. For something more durable, a high quality automotive clearcoat finish is nice (that's my prefered method) and can be found in rattle can quantities for small projects. For rust protection/finish on outdoor pieces, I'd say stainless steel would be ideal, if a little expensive. Below this, a good heavy multi-component paint system is best. The best system (IMHO) is a zinc based epoxy primer, followed by an epoxy color coat followed by a clear top coat. (This system will run you over $150 from Sherwin Williams as they only sell in gallon quantities). Below that, I prefer Valspar's oil based enamels (available at Tractor Supply amongst other places). It is also a multi-part system, although it is somewhat limited in premixed colors. The Valspar is also available in everything from rattle cans up through gallon cans. With any of these it is important to remember to get the steel good and clean either through powered wire brushing, or sandblasting. And also remember that the best way to apply the paint finishes is by air. I have a simple HVLP spray gun that works pretty well for general applications, although I would not want to use it on a custom auto or anything too fancy. While I'm NOT a professional painter, I'm not TOO terrible with a spray gun. I still end up with a few spots that need wet sanded and touched up, but I am getting better. There is definitely a knack to spraying paint My two pennies worth anyways. -Aaron @ the SCF Quote Link to comment Share on other sites More sharing options...
easilyconfused Posted November 28, 2007 Share Posted November 28, 2007 Just to add a point of safety, Linseed oil soaked rags have been know to self combust! Also, don't choose anything that is not food safe for food or kitchen items. Quote Link to comment Share on other sites More sharing options...
the_sandy_creek_forge Posted December 1, 2007 Share Posted December 1, 2007 AND to add a point of safety to his point of safety;) : The same goes for rags soaked with ANY type of oil or grease. Not sure if peanut oil will do it. But guess what? If you treat the peanut oil soaked rag the same as a rag soaked in 10W30, you'll get in the good habit of properly containing ALL oily rags (kinda like the "treat all steel as if it were hot steel" mentality). -Aaron @ the SCF Quote Link to comment Share on other sites More sharing options...
Blacksmith Jim Posted December 1, 2007 Share Posted December 1, 2007 I've been happy just rubbing hunks of bees wax onto the metal while it is black hot. One piece I have inside, I never used wax, and one day I took it down and sprayed a non-stick cooking spray on it. Maybe Pam. Wiped off the excess and put it back up. It looks surprisingly nice.

welder19 Posted December 1, 2007 Share Posted December 1, 2007 What is the best finish for kitchen utensils and things that will be used with food? welder19 Quote Link to comment Share on other sites More sharing options...
matt87 Posted December 2, 2007 Share Posted December 2, 2007 JohnB showed me a good one: sunflower oil. Wire brush the piece and gently heat to 'touch hot'. Apply a good but not excessive layer of oil with a rag, paper towel etx. You want enough to give a good coat but you don't want it dripping. Heat the piece again and watch out for a flare. The hotter the piece the darker the finish. Suppose you could probably use veggie oil, corn oil, peanut oil etc., but haven't tried it yet.

gerald Posted December 2, 2007 Share Posted December 2, 2007 I use vegetable oil. It's best to not use peanut oil on food items because peanut allergies are common. It doesn't take much to make some folks pretty sick. Quote Link to comment Share on other sites More sharing options...
skunkriv Posted December 2, 2007 Share Posted December 2, 2007 For food use items I have been using cheapie spray cans of olive or canola oil from walmart. Convenient and the oil stays clean til you use it. Lots of good tips in this thread but one finish I often like to use is none. On things that will be stuck in the ground or hung where it won't drip on the house after a rain I like a natural rust finish. Quote Link to comment Share on other sites More sharing options...
Ice Czar Posted December 22, 2007 Share Posted December 22, 2007 Boeing's LPS3 and a little Japan Drier LPS 3 Heavy-Duty Inhibitor is a specially formulated long term corrosion inhibitor which will protect metal parts stored indoors for up to two years. When applied it forms a soft, transparent, waxy film which acts as an effective barrier sealing out moisture, air, acid, alkali fumes and other corrosive elements.

Phil Dwyer Posted February 26, 2008 Share Posted February 26, 2008 The one thing about using vegetable oil one's supposed to be careful of is that it sometimes goes rancid. At least that's what the wood cutting board folks often say. They recommend a mineral oil. Quote Link to comment Share on other sites More sharing options...
Alan B Posted February 27, 2008 Share Posted February 27, 2008 I like to mix 1 tablespoon of japan dryer to 2 cups linseed oil then apply at a black heat. It dries quickly and leaves a nice flat black finish almost like seasoned cast iron. It is also food safe so I coat all my grills with it.

chyancarrek Posted February 28, 2008 Share Posted February 28, 2008 I specialize in making hand hammered serving dishes and I get my patinas using successive coats of vegetable oil to create a food safe / moisture resistant finish. The secret here is to paint the piece with oil in thin coats - not dip it. This is especially important with thin sheet stock as immersing it cools the metal too quickly for the oil to carbonize and it leaves it with a translucent soft coating. Heat your piece in the forge to between 500 - 800 degrees - Use a natural fibre cloth (don't use polyester blends) dipped lightly in oil. Bring your piece out of the forge and begin painting it on the surface (it will smoke big time - make sure you have lots o' ventilation and it'll flash at the higher temps so be careful!) but continue to paint it on in light coats until the metal starts to cool and accept it - the cloth will carbonize and add to the black color of the patina. Continue this until you get the result you're looking for - If need be, reinsert the piece in the forge until the existing oil starts to smoke - remove it and continue. This technique works equally well with any oil. For my purposes I hand sand and buff the piece to get the hammered texture to show back (see attached pics) I then wash it down with rubbing alcohol to remove any residue. If it's going to be a food contact piece, I rub on a thin coat of vegetable oil - If not, I use a satin coat spray lacquer. No worries about the veggie or olive oil going rancid. The oil is thoroughly cooked (like cast iron cookware) and even a light coat of fresh oil is ok because unlike wood, the metal isn't absorbing a deep layer of oil that lies there and rots over time. Soaking in Muriatic acid to remove scale and etch the surface really helps for creating a consistent patina. Because I don't paint or powder coat my work, I always tell my clients that my pieces are moisture resistant - not water proof. It will rust if left to the elements - I instruct them how to clean up light rust with triple-aught steel wool that's been dipped in vegetable oil. It's been a great technique for me - I've been using it for years and never had a return or complaint due to the finish on a piece failing.

Sandalphon Posted March 22, 2008 Share Posted March 22, 2008 So, If you are wanting an outdoor finish and want the metallic natural patina to show through, You would????? 1) Laquer or Varnish?? Or some other clearcoat for outdoors. Any recommendations on which ones work better? Quote Link to comment Share on other sites More sharing options...
Ice Czar Posted March 22, 2008 Share Posted March 22, 2008 Vanex Break-Through Clear Satin 50-0 1-800-851-7390 almost everything we do gets a flood coat of that, its real strange too, at first its this milky lavander, then it clears up as it dries, will darken a patina, and you can tint it as well. "normal" painting gets you a "frost" so it really is a flood coat, far heavier than you might normally do, just this side of dripping samplesvariegated rust panels 3 - Blacksmith Photo GalleryGeoffrey Newton Metalworks* you must throughly passivate any acids you used for patinas, they will show up like neon about the only thing that doesnt get coated with that is fireplaces (see my earlier post) (*note I just work there) Quote Link to comment Share on other sites More sharing options...
divermike Posted September 10, 2008 Share Posted September 10, 2008 I once applied wd-40 which is a fish oil base, the product came out nice, it was a bit uneven though, probably the handler, not the product. Quote Link to comment Share on other sites More sharing options...
NateDJ Posted September 10, 2008 Share Posted September 10, 2008 WD40 will NOT protect a piece from rust. I have a .50 Cal that I wish I had used something else on! WD 40 will evaporate over time leaving the metal unprotected. Quote Link to comment Share on other sites More sharing options...
CBrann Posted November 20, 2008 Share Posted November 20, 2008 For clear finish I use Helmsman urethane, from a spray can. Oil based For polished blades either mineral oil , (NON TOXIC!! FOOD SAFE!!) or camilia oil, don't know if its food safe. I also like any Rustoleum paint for colors. Butchers wax is good for things like plane soles or table saw tables, smooth machined cast iron Quote Link to comment Share on other sites More sharing options...
