I just bought a used 2007 CRF150f and the plastics are fairly scratches up. I was wondering if there is any way of eliminating these scratches without damaging them? The guy at the dealership wanted to sell me some special product but it was out of my price range. I was thinking about using a heat gun and sandpaper but I heard that if it is not done correctly I could make it even worse. Thanks to anyone with suggestions.
