More Details
Main highlights

TotalBoat

CA$94.83

More Details
Main highlights

- NEW IMPROVED FORMULA EASY TO MIX AND APPLY: Foolproof 1 to 1 mix ratio - just mix blue and yellow components until they turn green. Now easier to scoop, mix, spread, and feather to a fine edge; won't sag on vertical and overhead surfaces.
- HIGH-STRENGTH, LIGHTWEIGHT TWO-PART EPOXY FILLER smooths out the rough spots and fills the voids; ideal for filling and fairing dents, holes and gouges on your boat, canoe or other watercraft. Marine-grade putty is also great for home, rv and auto repair.
- CURES FAST. EASY TO SAND AND PAINT: Quick-drying compound is ready to sand in just 4 hours at 80°F; cured fairing compound sands even easier with improved formula; compatible with latex and epoxy primers and paints
- CHOOSE KIT SIZE: 2-PINT KIT, 2-QUART KIT or 1-GALLON KIT. NOTE: TotalBoat Gelcoat should not be applied directly over TotalFair or gelcoat will not cure properly. Before applying gelcoat, apply TotalBoat 2-Part Epoxy Primer or TotalProtect over TotalFair.
