I stumbled on an approach to hide those chipped cowl mounting bolt holes when I was assembling (not building ) an Aeroworks Edge 540T .46/.60 ARF. Aeroworks uses Ultracote. I just happen to use Ultracote for all of my covering needs so I have a ton of scraps. During the fitment of the cowl it needed to be installed / removed / installed / blah blah blah. The top two holes on the cowl sides (all holes provided by Aeroworks before the cowl was painted red) continued to look good while the bottom two started chipping around the edge exposing white gel coat. The top two holes have cub yellow trim on the cowl which protects the painted surface. I went upstairs and grabbed a hole punch. I put a strip of red covering on a piece of card board and ta da - beautiful circles just a tad larger than the screw head. A trim iron and those ugly little chips are history.
