My stealth sat a couple years and the pain has paid the price.

It has 3 problems.
Small chips and surface scratches. I figure I'll use a hard wax or mirror glaze to soften the effects of the bigger ones.

The other two problems are contaminants stuck to the paint and dulling of the clear coat.

Nashville has some nasty air. Over time a black sooty looking coating covers anything left outside a cover. Darn near have to sand it off.

Bug and tar remover has little effect. I have been scrubbing with nylon brushes but some spots are really stubborn.

Any preferred products or techniques that don't break the bank?
