I want something I can use on plastics inside and outside the car (OEM dash kit, transparent plastic in front of the odometer, clock/climate screens, taillights, etc. etc.).

anyone recommend a decent plastic polish that can accomplish all this? Thanks!

 

Two recommendations:
1. Plexus
2. Mothers Mag and Wheel polish - sounds strange, but it works.

I use the Mothers first and then follow with Plexus. Leaves plastics smooth as silk and protected. For heavier scratches, check out Nexus.

 

.....or renovo

 

I would recommend Plexus or Meguiars PlastX, both great products IMO.

 

Plexus is not so great at REMOVING scratches. It's not really a polish AFAIK. Try Novus Plastic polishes...I have #1 and #2...#3 must be REALLY heavy...

 

How about 3M Plastic Polish (and/or 3M Plastic Cleaner beforehand)?
These did a decent job on my headlamps and foglamps... for ****s and giggles I polished a gameboy color cartridge with it (worked great )

 

plexus really best used when used for maintaning plastics

 

try meguiars plastic polish. If you can't find it then get armor all protectant wipes.
