I have recently completed varnishing the bottom and topsides of the Rascal runabout. Here are some pictures:
The stain was Minwax Mahogany 605 Gel Stain. Put on with foam brush, waited 3 minutes and wiped off.
I put down 14 coats of Interlux Schooner Varnish over 2 coats of Interlux 1026 Sealer, with 220g wet sanding after 4 coats and 8 coats. Then 320 g wet sanding after 3 more coats and then after each following coat for a total of 14. The boat is now flipped over, and if it ever stops raining, I will stain and varnish deck. The designer recommended mahogany colored Sikaflex 241 for the seams on the deck, but a recent thread on deck seams indicated Sikaflex may not be the best choice. I checked the spec sheet for the Sikaflex 291 LOT that I purchased (replaces 241 Sikaflex) and it did say that it is not recommended for deck seams. Since I would like mahogany colored deck seams, what material is preferred? Here is a close up of the deck:
Seams are about 1/8" wide and 1/8" deep. I was planning on putting down about 4 coats of varnish prior to adding seam material, and then another 6 coats over everything. Any recommendation on the best method of filling seams is appreciated. Note that boat will be trailered and stored indoors, so UV exposure will be less than most boats. Could the Sikaflex work?
