A while back I thought to purchase new lenses for the turn signals and taillight because they were dingy and they would not look good.
Then I found Meguiars PlastX Clear Plastic Cleaner & Polish. This stuff works very well with minimal elbow grease. Needless to say, I am not in the market for new lenses. These things are now very shiny
This stuff works on the four turn signal lenses, taillight lense, the clear headlight cover, all of the reflectors, the clear dash plastic, the radio glass and the CLASS glass.
I love this stuff and thought I would pass it on to all of you!
PS. Do not use it on the windshield!
