Hey fellas, anyone get their valve covers powdercoated? I'm about to do mine, but noticed they have a rubber seal around the spark plug holes that isn't removeable. My question is if anyone nows if those seals will withstand the 375-400 degrees in the oven to cure the powdercoat fo 20-25 min. If they won't, I'll panit them with automotive paint and be done with it. Thanx for the help.
