Meguiers Plastx is good, but they also have a 2 part sytem (#10 and #17 if memorie serves) that is excellent. It is available at most good auto parts stores.
Wished I had snagged a can of Acrylic canopy polish while I was in the Force now that stuff was excellent.None the less , excellent pointers here .Thanks. OK Glen, I'll bite...what did you screw up
There's this here stuff that they sell at motorcycle dealers called Plexxus. Comes in a spray can, works great on plastic, lexan, whatever. Windscreens, helmets and visors, plastic body parts. I always felt that it would work nice on turntable covers and stuff like that. Never tried it though. It's more for the clean and shine than for taking out scratches but it does make an old piece of plastic look new again.
