I think the epoxy is kind of pricy too, and some extra work to apply.
Simple one part, water soluble polyurethane floor finish is inexpensive
(about $25 a gallon or so), fairly durable, and easy to apply. And
non-toxic. If you want color simply add artist's pigment from a art supply
store. I have used it and find it works well, I think Harvey Golden has
used it exclusively on all of his boats. I know others that have used the
two part polyurethane with good results, it make s very tough and smooth
finish. But is it pricey, and more complicated to apply since it is toxic.
I have also used hypalon, and if you by it in a larger bucket it is fairly
economical and durable, but it means you buy enough for about 4 kayaks,
small quality purchase is not worth it. It is fast and easy to apply, but
it does require a respirator and Xyline solvent (toxic) to clean up (I use
disposapble paper cups, rollers and brushes to avoid having to clean them).
I have also used left over oil based paint, and boiled linseed oil (with
Japan dryer added) on a child's kayak I built. These too have been
inexpensive, easy to apply, and so far have held up okay. Though I
understand it eventually gets brittle and cracks, requiring more coats, but
this has not happen yet after about three years (and both my daughters have
out grown it).
Another coating I have seen used and like, but have never used, is the
Sno-Roof coating used for mobile home roofs. It is sold in many large
hardware stores like Home Depot. It only costs about $18 a gallon, it is
non-toxic and easy to apply. It is a bit soft and does not have much
abrasion resistance, so you have to touch is up often. But it is a very
economical alternative.
Personally if I still did not have so much hypalon left over I would use the
one-part, water soluble polyurethane. Good luck.
