Sanded down my williams manifold and downpipe last night of surface rust. I want to spray it with a hi-temp coating but I have also bought some Hammerite anit rust primer. Will this be ok to use as a primer or will it bubble/crack etc under the heat?
Im going to be wrapping the exhaust after ive coated it in hi-temp paint and then adding a layer or to of some protective wrap paint when its all wrapped up!
