Mothers plastic polish is great and available at most automotive parts stores. It is quick and easy and only costs about 5 bucks for a lifetime supply. Happy polishing, Patrick
The best I've tried is definitely 3M Swirl Mark Remover. I know a lot of high end dealers use it. It works well for both acrylic and plastic dust cover. The effect normally last a few weeks.
McGuire's non-scratching automotive polish does a nice job. Then use regular car wax to fill in any deep scratches that won't buff out; they'll almost disappear. Clean up with Endust for electronics (spray in a can) & a lintfree blue paper towel.
