Am in the middle of repair on the interior gelcoat of my Nauset using the Spectrum patch kit. Color (whaler blue) is pretty good, but will be slightly off a shade or two. Not perfect, but better than looking at the black gouges down to the fiberglass. I have received excellent advice from LHG and have sanded the gelcoat flush with the surface using 320 grit. Am now ready to progress to 400, 600, 1000, 1500 etc.

Here's the rub (no pun intended) and the question. As I have sanded down to level, even with very small sanding blocks, I have also sanded a bit of the surrounding, original light blue gelcoat. The color of that original gelcoat is now considerably lighter than it was and much duller. As I progress to the finer grits, will the color and luster come back to its original? How much sanding do I do with each new grit and with how much pressure? How long should it take me so I can guage whether I am doing properly?

In one spot (on the transom shelf where the original stern light terminal WAS located and is now replaced with epoxy and gelcoat), I started to see a little black speck. As I sanded it a bit more, it got larger and I realized: "You cut through the gelcoat, dumb @*%!". I mixed up some more gelcoat and just applied it over the break. When I sand tonite, I'll plan on being careful not to cut through again as I sand down. IS THIS THE RIGHT APPROACH? Sure would appreciate some help from the pros out there.

Thanks, in advance.

time consuming and tedious work. Go from 400 to 1000. Then if smooth use a good rubbing compound and check your results. It will never be factory but you can get it real close.

Sorry. This should have been posted in Repairs / Mods.
