A question for the brain trust. A few months ago I took the exhaust manifolds off the Barracuda, bead blasted them, cleaned, and painted as per the instructions on the can (Bill Hirsch exhaust manifold paint). I baked them at 350 for a half hour, waited a couple days and put them back on. After several drives I have one small spot that I apparently touched before it was dry, or something like that. The paint flaked off. Other than that everything looks great.
I'm not going to take the manifold off again to repaint it. I think because the paint is only a four months old I can clean the spot and touch it up. Or should I tape it off and repaint the entire manifold?? I still have the same can of paint I used before.
My question, I know I run the manifold temp up to 350 to cure the paint. How many times to you suggest I do that?? I thought a few times running the temp to 350 letting it cool off for a few minutes and repeating. I know you guys will have a suggestion. Thanks in advance.
