My '04 has this buildup of residue or something on the tires but you can't see it. I used to use a gel from meguires but switched to a spray that I like better but my tires won't hold it, when I spray it on they get clumpy looking and just nasty. The car has 2300 miles on it. Not sure what I can do. I tried to wipe off the tires with a towel but it didn't seem to do anything. Any ideas. The only thing I can think of is to scrub the hell out of them but will that do the job. ??
