No need to apply gel coat Gerry. Prep according to 2000e's the bare fiberglass sanding and cleaning instructions. Once you have the barrier coat on they apply antifouling that has good reports for the area. Be sure to use a antifoul paint that has an unlimited dry time before launch (such as Pettit Hydrocoat, Pettit ViViD, Sea Hawk Cukote and as you noted Bottomkote). :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - www.freewebs.com/m15-named-scred/ On Thu, Apr 25, 2019, 6:11 AM Gerry Lempicki via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
To add gelcoat or not? Here's the deal; we stripped all the paint below the water line since we didn't know what it was, and it needed refreshing. I also removed a through hull, and redid a couple old through hull patches I found because I didn't like the looks of them. As we removed paint we found many areas (particularly under the lapstrake edges) where the gelcoat had been previously been sanded through. And of course I have the new repairs I did. Should all this have gelcoat reapplied over the fiberglass? I will be using Interlux 2000e primer, and maybe Bottomkote NT over it (not sure on that yet). The boat will be moored in fresh water for 5-6 months. Any thoughts on what should be done for proper protection/longevity of hull?
