Just wanted to post this. May be valuable to some and too minor to consider to others.
I picked up my new doors today from my friends "high end" paint and body.
When they were dressing the doors adjacent to the 90 and my friend was directing me on polishing methods to get the other panels to gloss up equal to the new, he offered some trade knowledge and even some info re faded/scratched light lenses (rear and front signal/brake etc . . .)
In the next "detail" phase I had intended to replace mine as they were scratched and sun-faded.
Instead he told me "dont be stupid" just polish them with glazing.
Well I came back and gave it a whirl. I removed the lens then used Maguires "Scratch X",
which is always great to have around the shop, I used a soft rag to rub out the majority of the scratches, then a bit of Maguires #9 Swirl Remover Glaze
and finally glossed them even more with Maguires #18 clear plastic
polish (which is a must for ST windows too)
15-20 min for all rears and I could not believe it. They look brand new!
Dont know why I did not think about it since I have restored / maintained guitars using the same method with similar compounds.
Just wanted to share since the forefathers here have assisted so much with my trivial issues.
