First of all, I don’t know if this will even work. I have a guy who wants the exhaust stacks on his big rig done in high-temp black (of course he wants black). Does anyone know how hot those babies get? He figures under heavy load they probably hit 700 f, but not sure how he arrived at that.
My other question is how much would you guys charge for 7″ diameter pipe assuming an average $25 a pound for the high-temp powder?
Also to do a total of 18 linear feet of the 7″ pipe, how much powder do you think I’d need? I’m guessing 3 to 4 pounds?
