This may have been asked before, so please don't roast me...
I just finished redoing the lenses on my headlights and I've noticed something. On all three cars that I've done this to there seems to be some kind of finish that has to be sanded through first before getting to the actual lens plastic. I do the refinish the hard way with sand papers and different bobbing and polish compounds from my other hobbies. Any thoughts on this...and is this what is included in the kits? And if so, can you buy just this "refinish sealant" by itself.
Thank you ...
