Bristol Finish Traditional Amber Urethane Varnish
Bristol Finish Traditional Amber is a two-part urethane wood finish for exterior and interior use, made as a long-lasting, low-maintenance replacement for traditional marine spar varnish.

Brush, roll or spray it over bare wood, epoxy-coated wood or sound existing finishes. Each kit includes Traditional Amber Resin (Part A) and Catalyst (Part B), pre-measured for the 8:1 mix.
