I knew in advance that I was leery of doing this...mainly because I love the look of the headlights on my car. So I had a feeling darkening them was not going to make me happy.
And, as of right now, I am on the fence. First off, I followed the instructions to the letter, but still managed to get some nasty streaks in both headlights. I'm thinking maybe I put too much on? The directions said "don't put too much", but it didn't really specify what the correct amount is.
Prepping the headlight: I cleaned the glass with a special made-for-auto glass cleaner from Stoner, PLUS rubbed it all down with rubbing alcohol. I then taped off the area using some generic-brand painter's tape.
Since my headlights are long and curved, I did long brushstrokes across the glass with the provided paintbrush, and edged the corners with the provided foambrush. The picture isn't at a high enough resolution to see the streaks, but you can definitely tell it is darker.
To compare the VEIL and the non-VEIL:
In an attempt to show the streaks, I tried to use the flash, with poor results. But I think you can get the idea.
I would take a picture now in the daytime, but of all the luck: IT IS POURING DOWN RAIN. So I don't even want to take my car out of the garage. So for now, you'll just have to go on my word that there are serious streaks. I can live with that, I guess, and hope to do a better job next time. But what IS bothering me is that the first headlight I did seems darker and "foggier" than the second. I am thinking about stripping it off and re-doing it. It makes it almost look as if moisture is trapped in the glass.
So, where did I go wrong? Or does everybody get streaks? I'll post updated pictures when I can bring my car outside.
