The high-solids formulation results in fewer coats required to reach the desired film thickness. As part of a gelcoat blister repair or prevention system, the formula incorporates Micro-Plate® Technology to reduce water migration through the epoxy to the hull surface which could lead to blistering. Micro-Plates® also provide corrosion protection for metals. Kit makes one gallon.
