I agree..base coat, clear coat urethane...all factory paints these days are extremely thin and won't handle much sanding..you might want to try something like old,cheap turtle wax brand polishing compound firstAs far as I know all TJs are clear coated.
Virtually all modern vehicles are clear coat. Clear coat is a two step, color then clear. Touch up is just a single coat.T I have to say, the paint does not look like it is clear coated and the solar yellow touch-up does not have a corresponding clear or so it seems. Maybe I'll try a test sand in a non-conspicious area.
