hey NOTAJP!!! I run Hella H4 5x7' headlights. Talk about expensive! $60-80 each!
I also have some PIAA 1500's on the front bumper.
Well in Colorado they use gravel on the roads for ice, and this kills headlights and windshields.....
I didnt think much of it, having only to replace one Hella headlight in 2 years, then all of a sudden in one weeks time I broke 2 headlights and 1 PIAA!!!
That cost me almost $300!!!!!!!!
So I found a solution......3M CLEAR BRA!!!!!
I got a scrap piece of 3M clear bra just big enough to do both headlights and both ffog lights from a local tint shop for $5. I took my headlights out and PIAA lenses inside and covered them all with the stuff.
2 years later, not a single chip/scratch or anything. NO yellowing, no peeling, the stuff works AWESOME!!!!!
If it was legal I would do my windshield, of course the wipers may not work so great on it, but it is perfect for headlight lenses.......
My buddy has a late 90's yota Cruiser and I know a headlight assembly for that bad boy was like $250.....$5 of clear bra could save you $$$$$$ big time......
