From what I've seen, our clear coat from the factory is pretty thin. If you've been using an orbital polisher then maybe you've worn through the clear in a few places, like on the high spots at the edges along fenders or the ribs on the doors. If you've just been hand polishing and waxing then I imagine the clear coat is fine and all the old wax is dulling the finish. Maybe try an orbital polisher and a compound with a mild cut. Also, you might check with an auto paint shop and get a nice professional polishing pad rather than those fuzzy wuzzy whilrly ones that come from WalMart. A good polishing pad runs around twenty to twenty five bucks if I remember right, but its worth it. They can also recommend an appropriate polish for the clear coat. I use the 3M products. Triathlete and I are going to be doing this same project in a week or so, and I can post what we use and how it goes if its any help.
Of course we'll have to experiment on Triathlete's truck first... ;eekg;;eekp;
