Waterproof
Made with the same resin as many boats, Bondo® All-Purpose Fiberglass Resin is 100% waterproof. This versatile product can help with numerous projects, including repairing tubs, showers, sinks, pools, hot tubs and boats. Replacing damaged tubs or shower units and having someone else repair your boat can be expensive, so complete a waterproof repair yourself! You can even repair cracked or shattered fiberglass when combining Bondo® All-Purpose Fiberglass Resin with Bondo® Fiberglass Cloth or Mat.

Structural Strength
When combined with Bondo® Fiberglass Cloth or Mat, Bondo® All-Purpose Fiberglass Resin is an extremely strong and durable repair method. It can handle any repair ranging from the smallest to the largest of projects. When the resin and liquid hardener are mixed, a reaction occurs which allows the resin to chemically bond to the surface you are repairing. This technological advantage of a 2-part system allows the product to fully cure in 2 hours and adhere permanently to the repaired surface. Not only can you save money, but you can make professional, great looking repairs.

Directions for Use
1. Clean repair area with acetone or warm, soapy water to remove all dirt, grease, oil and contaminates. Let dry completely.

2. Sand the surface with 3M™ Sandpaper 80 grit to remove all primer, paint, rust or gel-coat. Remove all dust created from sanding. Re-clean the surface following Step #1.

3. Pre-cut several pieces of fiberglass cloth or mat to extend 2-3 inches beyond repair area. Wearing gloves is recommended for the next steps.



4. Mix the Bondo® All Purpose Fiberglass Resin in a paper cup with the Bondo® 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. Do 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. Continue applying additional layers of fiberglass and resin as needed while the first coat is still sticky or wet. If the surface has dried hard and is no longer sticky, sand with 80 grit sandpaper prior to applying additional layers of resin and fiberglass cloth or mat.

6. Allow two hours to fully cure. Once cured, sand the surface with 3M™ Sandpaper 80 grit. Feather the edge of the repaired area with 3M™ Sandpaper 180 grit to blend the edges.


7. The surface is now ready for paint, primer or gel coat per the manufacturers’ recommendation.

8. Clean up using acetone or lacquer thinner. Store any unused hardener securely under the dome. KEEP OUT OF REACH OF CHILDREN.
