Directions for using Bondo Boatyard Resin:
1. Wash the area to be repaired with soap and water to remove water soluble contaminants. Allow to dry, then clean with wax and grease remover to remove any silicone or wax that could later cause failure.
2. Remove/Grind all paint or gelcoat by rough sanding down to bare metal or fiberglass. When possible, both sides of damaged area should be repaired for added strength. Depress or slightly bend in the edges of the solid metal around the repair area.
3. Cut pieces of Fiberglass Matting or Cloth to extend 2-3 inches beyond edges of damaged area to be repaired. Put aside for later use
4. Mix Bondo Polyester Resin as follows: Estimate amount of resin needed to completely saturate cloth or matting. Pour resin into clean container. DO NOT use waxed cup. If using 1/2 can, use 1/2 tube of hardener. For smaller amounts, use 14 drops of hardener per ounce of resin.
5. Lay Pre-cut fiberglass on a clean surface. We recommend a sheet of aluminum foil or other non-porous material for easy clean-up.
6. Use paint brush to apply resin-hardener mixture to fiberglass. A dabbing motion will help to saturate the fiberglass and remove any air pockets.
7. Place saturated fiberglass over damaged areas, flattening and smoothing with a plastic spreader or squeegee. Similarly, place a second piece over the first one. May require more than 2 pieces of fiberglass depending on size of repair and strength needed. Follow same procedure if both sides are being repaired.
8. Allow material to harden, approximately 1-1/2 to 2 hours at 75 F degrees until the repair is dry and cured. Curing will take longer at colder temperatures. To speed curing, use a hear lamp at least 18" from the repair for approximately 15 minutes. DO NOT OVERHEAT OR CRACKING CAN RESULT.
9. Sand with coarse paper or disc to featheredge. Prime and paint as you would a metal repair.
10. Paint brush or tools may be cleaned with lacquer thinner while still wet with Bondo resin.
11. Working life of Bondo Boatyard resin-hardener mixture is approximately 12 minutes. Mix in small amounts; never add/mix hardener with the entire resin can. For extended working life, use only 1/2 the amount of hardener with resin.
12. DO NOT USE RESIN BY ITSELF WITHOUT FIBERGLASS CLOTH/MAT
13. DO NOT PUT MIXED/UNUSED MATERIAL BACK INTO CONTAINER AS IT WILL HARDEN THE ENTIRE CONTENTS.
Polyester resins were the standard for fiberglass repairs and fabrication for many years... until the epoxy products were introduced. Polyester is less expensive and, in some instances, allows more latitude in mixing ratios of catalyst to resin. Epoxies are more expensive, but, in my experience, are also much more predictable and allow a broader range of applications such as filling, gluing, or fairing through the addition of thickeners or fillers. I am not sure what you mean by a "polyresin" canoe, but I suspect you mean "polyethylene". If so, neither polyester nor the "typical" epoxy resins will adhere and allow repairs. West System has introduced "G-Flex" which has been rumored to be used on polyethylene. Alternatively, check out the "welder" repair kits that use electric or propane heat to melt in a patch. Good luck.

I don't know what your application is but the Bondo resin is pretty much compatible with most composits.

I'm building an open rise set of steps using 3x12 wood covered with oak veneer. I like the high depth clear coat shine, also like to strengthen the steps and stringers. What can you recommend? I like to use some kind of boat yard resin.
