Can someone please advise on a clear coat for my steel sculpture?


Recommended Posts

Hi All,

A quick question.....   Can anyone recommend a clear coat to put on my intentionally rusted steel sculpture?   My other question is, do all clearcoats darken the steel?  I suspect they do.

Any advice would be greatly appreciated!

 

Thanks,

 

Simon.

  Hi Simon.  Are you trying to stop your sculpture rusting at a certain point in the rusting process?

  You know, pictures help! :)

Sorry about that.  More information would be helpful of course.  As you can see in the image, my Sculpture is of an Australian Wedge Tail Eagle.  He is made from Mild steel than his beak which is Stainless steel.  It is all thin steel really. His "Under body " is about an 1/8 of an inch but everything covering his body, as in feathers is 1mm.  Sorry I am not good with converting metric to imperial.

He is intentionally rusted but I dont want him to rust away completely.  Too many hours of work for that!  If there is no fix for this, I guess I have to accept that he is an indoor Eagle.

 Welcome to ifi, there's a lot of great people on here and lot's to learn.  Awesome sculpture!

Well, I was just asking out of curiosity and future knowledge.  I just let my sculptures rust, unless as you say it's an indoor piece.  This may be of some little help, a start anyway:

Nice work, beautiful sculpture!

I prefer VHT Flame Proof exhaust paint in satin clear for my sculptures. Over rust has been fine in my experience.  It has curing instructions but i have had good experience just air drying. Being outside, sunlight can really heat metal up. 

It does darken the appearance a bit. 

The hard part is getting it fully coated. I'd suggest being able to hang it different ways to get in the nooks and crannies with coats. 

Make sure the piece is Dry and Warm when spraying. A heat gun can help to prep the piece. 

I've also not had issues touching up spots later on that started rusting again because I didn't get into a crevice. 

I've used other clearcoats that just didn't hold up. I've not yet tried automotive clearcoat, but that is expensive and would need a flattening agent added if you didn't want high gloss. 

Another I have used was satin or matte clear Duplicolor engine paint in spray can. It worked well too. I just prefer the exhaust paint more. 

The name brands i mention are just the ones I have found to spray the best, dry fairly fast, and work well. Other brands may work as well. 

Hope this helps.

Welcome aboard Simon, glad to have you. If you'll put your general location in the header you'll have a better chance of meeting up with other members living within visiting distance. 

Nice sculpture, I like it. Do the "feathers" flutter in the wind?

Do you have more sculptures to share with us? We LOVE pics. :)

Thanks very much. That's great information.  I will see if I can source that locally here in Aus.  Do you have to apply heat to set it or can a hot day in the sun set it?

No need to heat to set it. Between 70-90°F roughly 21-32°C? it should be fine. I only mention heating the piece to remove moisture. I can tend to think in my local climate which has been cold and damp lately haha.

Don't be afraid to see what your local car parts stores are selling for exhaust or engine spray paint. Might be different brands but just as good. No need to import brands sold in the US. That could get pricey.  Try some locally available ones on test panels to see how they work and hold up. I'd rather test then jump in on a nice sculpture like that with no doubt a lot of time and effort. Also see how they change the rust color to make sure you are good with it. 

The eagle can live inside till you find a product that you are satisfied with. It is not fun wire wheeling off a clear and re-rusting. It just never turns out the same as the original coloring. 

I have also used the ones I mentioned on top of fairly cured color spray paint to good affect. 

I do notice there is little effect color wise on stainless. So that is good.

 

Other things I've heard used is boiled linseed oil that may need to be reapplied every so often, and darkens the rust color considerably more.

Like Das mentions above, I use BLO (boiled linseed oil) and sometimes tung oil, applied ambient temp, excess wiped and just bake in the sun. I find I need to touch up or re apply every 18- 24 months or so. I want to try Danish oil at some point- DO is simply a mix of BLO and some urethane varnish, something I could mix myself. I would just be concerned about the urethane component causing peeling.

Stash, one reason I think is heat. that is why I've come to engine exhaust paint. 

Funny enough, I've sold at shows where someone pointed out that the candles were melting in my candle holders. Metals get really hot out in the sun. Minus reapplying oils or waxes often, high temp paint is made for the abuse.

Guys, thank you so very much for your help, especially you Das!  The pictures are great and pretty well cover what I need.  Das, do you put linseed over your VHT?  I would have thought the hot sun would make short work of the Linseed?  Over where I am from we get some pretty hot summers, that's for sure. 

You seemed to like my Eagle, if you wish there is a short video of it here.

No problem Simon. I only use the VHT. I don't add anything on top. If you did add linseed oil on top you would not be able to touch up with the VHT again unless you degrease the whole thing and that would get messy and ugly. Stick with one product. The linseed oil was just to show a comparison in how it looks over rust. I can see how my one statement should have been worded better. I stated added linseed oil after.,  I should have said "added linseed oil to another section to show a comparison".

As of last I checked that linseed oil was still wet on the panel.  It would eventually dry in heat or sunlight. The Danish oil Steve mentioned might dry faster. I personally just stick with the VHT only. A sculpture that layered will likely need touched up after the initial coats. One solid coat is all that is needed but it is difficult to get into all the tight spaces. I would do some light coats spraying in towards the nooks and crevices then a solid outer coating. It sets up fairly fast so you can inspect as you go to see if you got it well coated. 

Thanks for the video with the info and more detailed pictures. Great work!

You should. They will hold up better. They will last a while anyway but I like to give them more of a fighting chance. Not only that but some people put the sculptures in their homes and most don't want to get rust on their hands when touching something. Even for non rusted metal it helps. If humid enough even the stuff I coat with bees wax, blo, and turps mix might start rusting if not reapplied once in a while. For most things the clear coat is a one and done.

  I'll try it out.  I was going to try painting some of mine in gaudy bright colors like those chickens, just to see if I like it, but I just can't do it.  I like rust too much, so I'll try your tips.  I've been making scrap sculptures for a while so some may have actually disintegrated a bit by now.  I use metal barrels quite a bit so who knows?

Thank you for the video Simon it was not only informative but well done. The music was a pleasant background I could hear you clearly over. Most people have music turned up so loud I can't understand them, even if I didn't mute it to avoid the pain. 

It also opened a real rabbit hole of further info about Waalitjs. I love a good rabbit hole to explore.

May we see more of your work, please?

Okay there it is, the rabbit hole that came up with your video shows more of your work and a couple shots of your shop.
