I presume that the paint has a layer of clear coat, although I am not sure about that. If I sand the layers of touch-up paint and then follow that with polishing compound, will it blend in properly if it has a clear coat finish? It is worthwhile to me to go to all of this trouble on the very visible chips on the top and seat tubes, but I wouldn't bother for some of the chips on bottom side of chain stays and the drops.
