Review on Novus 7136 Plastic Polish Kit by John Invert

Just a little is great for heavy scratches and rubbing, but be careful with small scratches! It did a great job on the severe discoloration of my headlight lenses and vinyl window tint. I used a little to clean the dashboard lenses which had small scratches and they scratched the entire lens. I had to do a lot of post-processing to try and restore it to its original clarity. Finally I finished it off with Meguiar's ScratchX and that cleared it up. I'd suggest only using them for heavy scratches, but if you only have minor scratches on the dashboard plastic, maybe just stick with light, simple plastic bumpers like Meguiar's ScratchX, etc.
