Marine High Strength Repair Filler

Originally called Blister Repair Putty, this two-component vinyl ester filler is formulated with short strand fiberglass for semi-structural repairs above and below the waterline.
Good for repairs of fiberglass hulls, decks and other parts: filling scratches, cracks, and gouges, fairing and bonding.
Note: All epoxy resins must be removed prior to application; epoxy will inhibit cure and adhesion.
This vinyl ester resin filler is unique in the marketplace.
Unlike polyester fillers, it doesn't absorb water, and provides excellent below the waterline performance.

• Fast curing

• NOTE — Do NOT use other brands of hardeners with 3M™ body fillers and glazes — testing shows that a variety of failures can occur
