4. Mix the BondoÂ® All Purpose Fiberglass Resin in a paper cup with the BondoÂ® Fiberglass Resin Hardener. For small applications use 10 drops of hardener per ounce of resin.Working time will be 10 to 12 minutes. For larger applications, use half of the fiberglass resin hardener supplied, to half of the resin container.Using large amounts at one time will cut the working time in half of the mixed resin.o not mix the entire container with liquid hardener. Mix thoroughly. 5. Brush a coat of the mixed resin on the damaged area extending 2-3 inches beyond repair. Place the first layer of fiberglass cloth or mat onto the resin application and immediately apply another coat of resin over the fiberglass cloth or mat.
Process: As you already know, it is going to take a lot to get this down to a mirror glass like smoothness and shine. The 1st step, and literally every other step from now on is sanding. Start sanding your fiberglass with some low grit 36 or 80 grit sandpaper.Always use a palm sander, or a sanding block, only use sandpaper in your hand when you can use a block. Your fingertips will unevenly supply pressure causing streaking. Sand the whole area until you get a less rough more even area to work with.nce you have a fairly spot free and smooth area, use your spot putty on the little pits and valleys. It is a really good idea to use your finger or a razor blade to go over and smooth those out. Sand again with a very high grit sand paper (400-800).
