Simply mix POWER FIBER with its cream hardener and prepare as a body filler, with a spreader and mixing board. The balance of resins, strands, micro fibers, plasticizers and polymers eliminate the need of fiberglass mat as reinforcement. RE-VIVE is a polyester resin based compound that If using a graduated cup or a straight-sided can, get in the habit of measuring the same way each time. If you pour the resin first, then always pour the resin first. Before adding the hardener, notice how much resin is already in the container, divide this by two (for a 2:1 system) and then add hardener to bring the total to the correct mark. Bondo® Fiberglass Resin is a strong material commonly used for autos, boat building and other repairs. This high-strength polyester resin can be used with fiberglass mats or cloths on surfaces including fiberglass, wood, metal and masonry to repair metal rust-outs and to recreate or join surfaces. Bondo - Home Solutions 0.74 fl. oz. Fiberglass Resin Liquid Hardener - Use as a bonding agent- quickly and easily create a bond between multiple surfaces. Concentrated liquid fiberglass resin formula. Easy application. - THD SKU# 312213 Hardeners are used to cure epoxy resins. However, simply adding a hardener to an epoxy resin may not cause the epoxy mixture to cure quickly enough. If this is the case a different hardener may be required. Also, hardeners with certain additives can be used. These hardener additives serve as catalysts that speed up the curing process. Polyester resins are the most commonly used matrix in the marine and composite industry. These resins are styrene-based, flammable and catalyzed when combined with Methyl Ethyl Ketone Peroxide(MEKP). I don't know if the MEKP catalyst degraded over time, or if I just didn't mix things correctly, but that's the point when I gave up on fiberglass resin and used Sintra instead. I doubt that you're going to be able to get the resin to harden up after the fact, even if you somehow mix the catalyst onto the goopy resin currently on the pepakura bio.

Free technical advice Re: Resin to hardener Ratio I just finished a stringer/floor/transom replacement. Being north of the border, I can tell you what I used, but it is in metric. At about 70 degrees F, use about 7-8 ml's of hardener to one litre of resin. If it is a little warmer, maybe use 6-7 mls. Thorough mixing of catalyst into resins and gelcoat is very important. Also the correct additions should be observed to maintain good results. Dispensers are advised for accuracy. The table below gives the correct ratios of catalyst to resin and gelcoat by weight. 1% is considered a slow mix, 2% is ideal, 3% is a fast mix.
