Finish Work
There are all sorts of steps at this point that don't warrant a complete section.
Gloss Coat
When making a kayak from a mold, a layer of resin is applied before laying down glass that is called a gel coat. Its not clear whether this is the best term for the final coat of a boat of this type of construction. Since this boat is more similar to a surfboard in construction I'll call it a gloss coat, but either way the goal is the same, a shiny finish coat. Each side was masked off with tape prior to coating, and the tape removed while the resin was soft but not runny.
I did the deck in several stages, first a thin coat that I then sprinkled the glitter onto with a large salt shaker. Then once this was tacky a thicker cover coat. Unfortunately some of the copper flake stuck through this second coat, so a third was needed, which involved more sanding (as I let coat #2 cure before I realized the copper sticking through).
The bottom I did as one pretty heavy coat. Because the bottom was not completely flat, it did run some off the nose. At the stern I had made tape dams to hold the resin from running off to create hard edged rails. Unfortunatly the stern rocker resulted in too much pooling and really thick edges to one side because the boat wasn't level. I later had to grind this off with an automotive grinder, and finished creating the hard rails by putting tape along the bottom edge when I did the final deck coat (letting it run down and out onto the tape.
I then wet sanded with 320, 400, 600 grit wed/dry sandpaper. Then auto polishing compound and a coat of wax. This finish wasn't a super mirror finish (like out of a mold) but very smooth to the touch and a good lustre.
Finbox finish work
After the bottom gloss coat, I used a heat gun and utility knife to cut out the finboxes. Its important to push only down with the knife and not saw up and down because you will get some delamination from the top of the finbox. I also then sanded the edges down to an angle so that less would catch on them. Small amounts of resin got in despite the baking flour (which I simply vacummed out) and this needed to be scraped out.
Inside
I was not going to fiberglass the inside, instead I painted it with epoxy with sealing additive (west system, aluminum powder) which is supposed to increase waterproofness. I did end up fiberglassing just the floor and seat area however, and the fiberglass I used for the cockpit rim extended inside some 4 inches. After taking the boat out for the first time I also realized that when carrying it on my shouder, my elbow bangs pretty hard into the sidewall of the cockpit area, so I put some fiberglass patches there as well.
The cockpit rim was sanded down, and several coats were painted to smooth out the edge when I was doing the inside.
Outfitting
Outfitting is still ongoing. I plan to carve a full minicell seat eventually, but for now I put in adhesive thigh pads, a simple seat pad, and a foam backrest and foam bulkhead. Its pretty comfy but not as tight as I eventually want to get it.
