Good call. After I renewed my headlights with a 3M kit they would start to yellow in a couple of months. Throw some of this on the 3M kit's buffing pad and spin it on the headlight with the drill. Takes the yellow right off.Product: Meguiar's PlastX Clear Plastic Cleaner and Polish
Description: Use for polishing plastic headlight lenses such as on the 9-3SS
Price/where to buy: $7.00 Amazon
Pros: works great at removing fine scratches on headlights without using the heavy-duty sanding kits
Would you recommend it? Yes
Product: Dupli-Color's Tire Shine Coating
Description: A non-silicone wheel shine coating
Price/where to buy: $8.99 @ Autozone, O'Reily's, etc.
Pros: Lasts a very long time. 8 weeks or so. Not silicone based. Meaning there is no run, no sling, no greasiness.
Cons: Overspray but...I have this great method.
Would you recommend it? I absolutely would. At first I kept walking by this product as it has these terrible warnings about overspray getting on wheels or body. 2 pieces of cardboard provides a simple solution so you don't need to worry about this. I cut out one piece that I drape over the top of the tires and a second piece, a circle the diameter of my wheel that I hold in place while I apply the product. All wheels are done in minutes without worry of overspray. The products cures in moments to a nice black with a very unique, adult, dry shine. You can touch it. You can wash it!
Don't recommend it! Put in and after 3 to 4 days it flows on the paint, very disgusting! Won't stay in the rain! Holy crap! The worst product by Mother's by far!Product: Mother's Back to Black
Price/where to buy: any auto parts store
Pros: Beautiful shine, long lasting, gets rid of greying
Would you recommend it? yes
Used it on the back plastic trim and various plastic trim around the car. Wow, what a difference! Armor All...no thanks!
