Agreed, Bob C. One can only 'correct' a clearcoat to remove imperfections and apply a polish, sealant, or protectant overtop. The way to do that is use a corrective polish like Meguiars 105 / 205. Of course the average clearcoat thickness is less than that of a post-it note... It is typically good form to routinely protect any clearcoat, cause once it's gone the only option is refinish.
Meguiars All Wheel Cleaner is a wise choice for a cleanup on clearcoated wheels. I've had good results with it. Waiting too long to remove brake dust (especially that of OE pads) from aluminum wheels can result in nasty pitting. Same with some of the harsh road chemicals in use. Check my profile under wheel refinishing to see the worst of it.
