Hi all, ive tried searching but i wasnt able to find an answer. I was wondering what cares to take when polishing an oxidised/faded plastic bumper. i have a megs g220 and im learning to use it with some good results. i have a '90 mx5 and want to get it looking great. Is it ok to use my other polish's on plastic like i use on the paint over metal? ive had good results with colourx by hand in the past and i also have mothers plastic polish i can use. Thanks for any tips
