Where to use TotalBoat fillers

Milled glass fibers are commonly used when epoxy must fill a void, provide high strength, and high resistance to cracking. Examples include structural filleting, bonding hardware, and keel bedding. TotalBoat fillers can be used with either epoxy or polyester resins to change the resin properties for various uses, such as bulking out the resin or making it easy to sand. Because fillers can affect the pot life of a resin, create a small trial batch first to determine how much working time you’ll have.
