Use this colorless creme hardener with virtually all polyester filler products like Bondo or Body Icing, Minwax or Everhard, etc. Lets you mix your repair fillers to the color you want using the PolyFil powders and then harden them without shifting the color. No more wondering what the final color will be if you mix the 'red' or 'blue' hardeners that usually come with the fillers when you buy them from the store.
Not for use with fiberglass resins or epoxies.
