: Hi Todd

: Are you adding further epoxy coats after you have sanded your fill coats? If
: you are I wonder why. Why not just varhish? Adding further epoxy coats is
: just adding extra weight?

: Et

Working two boats at once. I had a fairly thick epoxy base (5 coats, counting seal and wet-out) on the hulls (no fill coats on the decks, yet), of which I ROS'd one hull smooth. In doing so, I turned a lot of epoxy into dust. I tend to lean towards the side of over-built, and thinking I'd like to replace some of that rock-hard epoxy that I just removed, only aiming for a smoother finished surface this time. I'm looking at varnish as nothing more than a UV protector for the epoxy. I've no problem conceding a few onces of weight in epoxy for superior structural integrity and better surface protection. So far as the weight goes, I'd rather it come off my winter's fat a-s, as there's certainly more there to part with than what I might shave off the boats!

In trying to strap together the hull/deck of the freshly sanded boat, I've learned that strapping tape doesn't stick nearly as well to sanded epoxy as it did to un-sanded. So I'll just sand smooth the joint area for the seam tape on the other boat, and clean-up the fill coats after seaming.

With respect to epoxy application, I brushed on my seal coat, squeegeed the wet-out and rolled the fills. Seemed like all of them had runs, but then I wasn't necessarily trying for thin coats, either. I'll try both the squeegee and tipping off the roller to see if I can get something a bit more controlled. And if anyone has more ideas, I'm all ears. I'd even pop for a quart of fast hardener if I thought it might be better to deal with. The slow hardener is sssssslllllloooooowwwwwwwww.
