Plastic Body Filler Mixing Palette 12" X 12" (2 Pack)

These reusable mixing palettes are one of my favorite little bodywork essentials. They give you a clean, smooth surface for mixing Bondo, body filler, wood filler, glazing putty, epoxy, and other materials without wasting disposable mixing boards.
 
The best part is cleanup—once the filler cures, just bend the flexible palette and the hardened Bondo pops right off. I reuse mine over and over, which makes them way more convenient than constantly going through disposable mixing surfaces.
