Great for Filling, Fairing, and Repairing Composite Surfaces
TotalBoat Polyester Fairing Compound is easy to work with, easy to sand, and provides optimal strength. It's ideal for making quick and easy cosmetic repairs to fiberglass and gelcoat surfaces. Just mix with MEKP catalyst, apply easily with a putty knife, wait while it sets up quickly, then sand.

This lightweight polyester cosmetic filler is primarily for use in tooling and repair applications as a fairing material only, and is not designed for high-strength repairs. For structural repairs requiring strength and dimensional stability, you can use TotalBoat Polyester Structural Repair Putty, a high-strength, fibrous polyester putty for filling larger cracks & voids. After it cures, apply TotalBoat Polyester Fairing Compound over the repaired area, let it cure, then sand to achieve an extremely smooth surface ready for gelcoat or paint.
IMPORTANT!
TotalBoat Polyester Fairing Compound is for use above the waterline only, and can be overcoated with gelcoat or paint. If used below the waterline, it must be overcoated with TotalBoat TotalProtect Epoxy Barrier Coat Primer, to prevent water damage.Technical Information

Shelf Life
Polyester resins have a limited shelf life and will, over time, harden in the container without the addition of catalyst. Shelf life is dependent on a number of factors such as product formulation and storage conditions. As a general rule, the shelf life for uncatalyzed polyester resins should be up to 6 months when stored in dry, cool conditions below 70°F. Warm to above 60°F before use.

This product was relatively easy to apply, but a bit messy. Even when cured, it was fairly soft and tacky. I understood it should still be tacky, but compared to the laminating polyseter resin, it was *very* tacky and soft. I definitely went through a lot of sandpaper removing the excess. If using this product, try to get as much excess with the scraper as you can to minimize your sanding.

Product comes out bright white and does not take wood stain. It can be sanded readily as advertised but make sure you are wearing a mask while doing so as the fumes are noxious.
