Powder coated my AirGap

I wonder if it will yellow with the heat like clear gloss paint over aluminum. I’ve cleared them and painted them. The clear gloss has always yellowed some but the colors seem to hold up better. This has only applied to painted manifolds not powder coated. That really does look awesome with that black block and polished valve covers.
Don't know if it will yellow but i do know that gasoline will stain it permenantly!!!
