I did mine with Lamin-X, but it doesn't look as yellow as yours. Also, does your tint actually tint the color of the light the fog lights emit? Mine only mildly subdued the bluish white of my LEDs.
I have no idea what i used for my fogs lol. It was some random cheap film from Ebay...like 4$ or something? haha but its been holding up perfectly and it does change the color of my light. It actually looks really yellow, especially because it contrasts with my slightly blue (5000k) Hid's.
Don't feel bad, I think my car has a fetish for eating bugs. Every time I wash it, I have to spend an extra 10 minutes scrapping those little bastards off.
