Bondo® Fast Dry Filler instructions:
Step 1: Clean all surfaces with soap and water followed by a low VOC compliant cleaner. Allow to dry.

Step 2: Sand the damaged area with 80 grit sandpaper to remove all paint, primer, and rust down to bare metal. Sand 1-2 inches beyond the damaged area. Clean again with a low VOC compliant cleaner.

Step 3: Stir the filler before using. Knead the hardener tube. For a 3-inch diameter puddle of filler, squeeze out a 3” long strip of hardener. This is the maximum recommended amount to mix at any given time for optimal application. Mix thoroughly to a uniform color on a clean, non-porous surface. When product is mixed, the working time is 3-4 minutes. Do not add hardener directly into the filler container.

Step 4: Spread an initial thin layer of the mixed filler over the repair area using firm pressure to ensure maximum adhesion. Apply additional layers of filler as needed. Allow filler to cure 15 minutes.

Step 5: Rough shape the filler with 80 grit sandpaper. Finish sand with 180 grit and finer. Featheredge the repair. Wait 45 minutes and apply 2-3 coats of primer to cover the repair area.

Step 6: Apply Bondo® Fast Dry Filler to fill in small imperfections and re-prime with 2-3 coats. Follow paint manufacturer’s recommendation for priming and final finishing.

For best results apply at 45°F (7°C) or above. Do not put mixed filler back in the can. Clean tools with acetone or lacquer thinner.
