System Three corporation makes a special, extremely low viscosity epoxy, formulated specifically for sealcoating. They describe it as being very safe to use, and much stronger than other sealcoat products. I've used their standard resins, and have found them to work quite well;I intend to use their sealcoat product for my boat, when I get to that stage in construction.
