also, if meguiars ultimate rubbing compound is really good for oxidation/fine scratches/swirls/etching etc... I have had and have seen great results from using this even by hand... try it.. takes a little elbow grease, and yes it does take a minute amount of clear but that is the only way you are going to fix the deeper paint defects... give it a try. I think meguairs offers money back anyways, and crappy tire will honor that... if that doesn't work, maybe you should bring it to ken for some porter cable action
