After reading this thread: https://www.iforgeiron.com/forum/65-gas-forges/?do=add, I contacted Wayne to get some metrikote, it arrived yesterday (Thanks Wayne!).
This is a Majestic Forge 3 burner "knife maker deluxe" and this is what I found when I got it opened up to paint with metikote. The Question is.. Do I need to re-line this forge given all the cracks in the insulation material, or just paint it?. It feels a bit like very dense polystyrene (Styrofoam) and is about 1 1/4" thick, 1 inch at top around burner ports. the bottom seems to be firebrick.
thanks
