Can you use Gelcoat to touch up over Awlgrip?
Or is this not a good idea?

My gut tells me that is not a good idea.

check your local automotive paint supplier store. It will be the one that supplies paint and body repair products to the car dealerships and independant body shops in your area.

Best bet for paint match, is to tow your boat right to the shop and have then analyze the color with a portable device which then downloads the info into their computerized mixing system.

Surprisingly, I believe you can order from West Marine all three parts. It is not cheap.

Please doublecheck this with any of the companies that sell marine paints/gelcoats, but I believe that there is a problem with using gelcoat over Awlgrip, being that Awlgrip is an epoxy based product and gelcoat is a polyester based product. I just recently ran into the same problem after having done a lot of fiberglass repairs/renovations with West System Epoxy and wanting to finish the job with gelcoat. The guy who will be painting the boat informed me that I couldn't use gelcoat (polyester) over epoxy resin, because the chemicals won't tolerate one another. I wouldn't settle for that being the end of my months of hard work, so I investigated via the net and ended up contacting several different manufacturers of various gelcoats/paints/etc. Before long I was informed that the job could indeed be done if I would simply use a tie-coat, several manufacturers (s.a. Ferro) or by using a vinylester primer as an intermediary between the epoxy and the gelcoat. I believe that this is probably what you will have to do as well in order to get the gelcoat to adhere to the Awlgrip. Good Luck. Jed
