Anyone use Lexan?

I didn't have good luck, with the higher dollar margaurd (more expensive lexan that is suppose to be higher scratch resistant) it scratched bad if not worse then regular lexan.
I use only Polycarbonate (Lexan)
Here is a trick, you can polish out scratches, and even lacquer thinner marks with a headlight polish kit. I used the Mothers brand kit sold at Walmart.
I accidentally touched my new lexan glass with lacquer thinner on my fingers. The kit comes with wet sand paper,polish, and polishing wheel. I used each step like instructions say, everything polished out perfect.
Also, don't use plastic paint, use real paint. I thought it would be better, and it blistered right off the back once I went into the sun.
Here is where I got my lexan cheap:
