I'm just finishing my second boat. Spidey does it just about the way I do. I've got just a couple comments to add. I switched to Raka epoxy from Poxy Shield (from Glen-L) because it is much thinner and has no color. It wets-out so much easier and tends to trap bubbles less when working the cloth too much or too fast. I only use a squeege when wetting cloth. I found if there is a spot that doesn't want to wet, I just wiggle the cloth back and forth very slightly with the edge of the squeege it wets out instantly. I use the slow hardener to wet-out and the fast to fill.
I use half a roller (the thin yellow foam ones) to spread fill coats then tip-out with a foam brush. Be sure all edges of the wood are sanded. Rough edges tear little bits of foam off the brush that will pepper the wet epoxy. If all goes well with the wetting-out and the fill coats, I keep adding fill coats as soon a the previous coat sets to a firm flypaper tack. Saves a lot of sanding. If its more than 24 hours between coats or a blush shows up then I wait for a hard cure (won't dent with a fingernail) and sand with ROS 80 grit between epoxy coats. I wash the sanding dust off with ammonia water. A solvent wipe with lacquer thinner also works but I perfer the running water rinse with the ammonia. Be sure the epoxy is hard cured before wetting, the Poxy Shield fogged on me in a couple small spots. Don't touch the prep'ed surface between coats or wear cotton gloves if you must. Keep all oils and mists out of the work area.
Fairing boards are best for fairing the bare wood, but I'm hung up on scrapers for fairing epoxy. They are great for kncking off the hard fuzz on the seal coat before the cloth. They are also good for fairing out any epoxy waves. I always scrape two directions 90 degrees to each other to eliminate the epoxy waves in both directions. I can scrape the whole deck in 30 minutes if the epoxy is 12 hours old. Scrapers are the best tools for removing epoxy runs.
After the scraped epoxy hard cures I sand to 150 grit before varnishing. I wet sand with 220 grit between varnish coats.
There are a dozen ways to do this stuff. You just have to find what works for you.
