Non Yellowing Clear for Engine Parts
Friends of mine have used clear (PPG) to paint a new intake and it yellowed. From that point on , they never use clear on intakes. I want to clear it a two piece aluminum timing cover (Rocket Racing). I polished it but the material is soft and scratches easily. Does anyone have a known clear that will not yellow in this situation? I may end up powder coating it but trying to save some cash. Is there is a good clear that will also do the job? I have hi-temp engine clear and also some wheel clear (all spray cans), but don't want to get into a two month ok, and then it yellows.

The substrate / surface has to have a tooth and be 100 percent free of contamination for the top coat to have proper adhesion.

I wanted to keep the polished look and protect with the clear. I have used that aluminum paint in the past for alternators with good success

I used BASF (Glasurit and/or Diamont) over the years. Did it yellow? Unfortunately I’m not sure because it was usually over gold basecoat. I can say that in the relatively few that retained exhaust crossover heat, it held up pretty well. Not perfect, but well. I saw no apparent yellowing over BBO blue but can’t say that it didn’t. Sorry, not that helpful, but figured I’d throw it in here.
