Exhaust manifold surface?

Postby GregM » Mon May 21, 2018 6:41 pm

Should I prep and paint exhaust manifold surface with prep and paint with 500 degree paint or go bare metal with the gasket?

I would paint, but high degree paint not necessary. Paint on the bottom where it bolts to head will burn off no matter what you use - the rest does not get that hot. I always use a sealant with the gaskets to fill in all the nooks and crannies - others may not. Just re-read your email. If your talking about painting the mating surface, I would not. Just bare metal.
