Which TotalBoat filler is best for my epoxy project?

TotalBoat fillers include TotalBoat Glass Microballoons, TotalBoat Silica Thickener, and TotalBoat Milled Glass Fiber. You can blend these fillers into epoxy or polyester resins to change the properties, depending on your project needs, such as making the resin easy to sand, or thickening it for fillets or glue-ups. Keep in mind that a filler can affect a resin's pot life and working time, so it might be a good idea to create a small test batch before using the mixture on your project.

The table below shows which TotalBoat filler is best to use for various types of epoxy projects.
