I just got my valve covers done in wrinkle red, and the dude did the inside of them as well, this a bad thing? i tried hitting it, scratching it, etc and it's not coming off at all, so i'd assume it wouldn't come off in the engine just scares me some, he says he does it on every set he's done and never had an issue. anyone else have this done and have it get in the oil system? I had NO idea where to put this thread so mods can move this whereever just had to do with oil in a way so figured i'd start here.
