Re: Powdercoating Valve Covers? (jerkyboy)
I may have been involved in one of those posts Vinnie mentioned, as I had a bunch of stuff powdercoated and I wanted the valve covers to match. My buddy owns a powdercoat company (and owns a Chevelle showcar) so he took kind of a special interest in my parts. He told me there were too many bubbles and airpockets in these mag valve covers, and when they're baked at....... what.....450* (I forget now) these voids release to the surface and screw up the finish.
At any rate, what my buddy did, was bake the valve covers at 300* or so to release the gas, then filled and sanded them, then did it again just to be safe. He then sprayed them with a heat resistant paint and baked them at 200*, and they turned out great......... much more durable than if we hadn't baked them. I have heard of guys powdercoating these valve covers successfully, so it could be that my Bro was being a little too careful with my parts, but heck, there's nothing wrong with that :D
I tried to look up that thread so I could link it, but the search feature is crappy........imagine that....... :jester Here's a pic of the finished V/Cs:
