The resin half of our Thick 1:1 epoxy system, sold on its own. Same high-build, no-sag formula as the kit: it grabs a vertical surface, bridges a gap, and builds real film thickness in one pass instead of three. This is the bonding and fillet resin, not the laminating resin.

Bonding and fillets. Structural glue joints, fillet radii before tabbing, gap-filling bonds on wood, fiberglass, metal and masonry.
High-build coating. Holds thickness on vertical and overhead surfaces without running.
Hardener options: 1:1 Thick Hardener is the no-math path. It also runs our 2:1 slow for hot days and big batches or 4:1 fast for cold weather. Mix at the ratio on the hardener bottle.
Fillers: takes fumed silica, milled fiber and microballoons for putty and fairing work.
Not for wetting out cloth. Too thick for glass, carbon or Kevlar®. Use Thin Epoxy Resin to laminate.

Scuff sand and solvent wipe any surface before bonding. Not UV stable, so topcoat anything in the sun.
