What do you guys use on the plasic things that have been chromed on a car, such as the decals and emblems? Are regular metal polishes going to be too abrasive?
Try using a cleaner/wax. If you have ever purchased a clay kit like Mothers, the small cleaner/wax bottle is good for keeping in the car for water spots too.
I've used Mothers Chrome Polish with good results. I wasn't sure if it was going to work, but I had some laying around and it worked great. I might be able to pull up some before and after pictures later tonight.
GLARE is my favourite for plastic chrome Though you can use abrasives on them with an orbital I do that alot. Menz 106FF and RD on them is spectacular
If you just want to clean and protect it Klasse AIO works good. I never use a metal poslish on it if it's in good shape.
