I need to hear from those of you with fiberglass experience:
The thing is that the radiant heat from the exhaust manifold on my turbocharged VR6 has overheated the lower engine cover. I do have a heat shield solution coming so the time has come to restore/refinish the engine cover. You can see in the pics how the manifold has overheated it.
So what is the basic process? Will sanding (coarse => medium => fine) suffice? If so, what grit sizes should I go with? (Although I suspect I will need to grind down the bubbling...) Any gelcoat needed? My cover is/was painted with a fine hammer finish. Is that pretty typical? Any specific type of paint recommended? Is primer needed?
