after years of wear I was barely able to see out the rear plastic window in my tj at night or in the day. The windows were faded over time and damaged from being rolled up and scratched when dirty. I have tinted windows so it made things even worse. I remember seeing the novus 3step scratch removal in the jeep catalogs and I figured id try it out. I stopped by a local plastic store called Tap plastics and picked up the #2 Fine scratch remover (as recommended by employee) for $6. I applied first coat and buffed with a 9" orbital buffer. When I wiped it clean, I was shocked at the difference. I could actually see my radio and dash through my rear window. I applied and buffed 2 more coats and only The really hevy scratches are left. I plan to return to get steps #1 and #3 to finish it off. The difference is night and day. Recommended??? Hell Yeah!
