I found a product call Flitz that says it is for Metal, Plastic, fiberglass and restores paint. It works well for me on everything I have tried it on. Got it originally to polish out an acrylic watch crystal. Worked very well for that and aluminum. Very mild fine polish. Takes a little time due to being so fine. Due to being so fine it will not take out deep scratches. Would need to sand with 600 or finer sand paper first. I found it in a local knife shop or you can go to www.flitz.com.
