My headlight covers came today and I have tried coating them twice. I follow Veil Guy's video as best I can, clean everything impeccably, use the right brush, and I'm even doing it in a nice climate controlled apartment. No matter what I do I get at least one big hozitontal streak across the cover where the stuff just stops flowing 2/3 of the way down. Keeping a low profile is very high on my list of priorities and this just isn't cutting it. Effective as this stuff may be it's just too damn difficult to apply properly, especially to large surfaces such as these 28" wide headlights.
I'll give it one more shot after my frustration subsides, and this time I'll try it with the cover horizontal rather than vertical. After that I'm just not going to bother anymore.
Alright, done ranting. Sorry.
