Bondo Fiberglass Resin Repair Kit, 00422, 0.9 Quart

It worked just like the instructions and the multiple online reviews said it would. It was actually fun to use. A few recommendations: (1) If this is a first time for using fiberglass, read others' reviews of this kit plus some online guides on the hazards of fiberglass lay-up and then watch at least several videos on fiberglassing techniques on YouTube. Be aware that some of the videos contain errors. (2) If used as directed, this kit is safe. However, there are multiple fire and health hazards involved in using this kit if you are careless. Wear a face mask filter designed for working with fiberglass and a pair of eye protectors. Exercise caution with what chemicals you are mixing, and prevent the spread of fibers from the cloth and/or dust from sanding dried fiberglass. Before laundering clothes that may have fiberglass in them read articles on laundering clothes after working with fiberglass insulation. (3) To make sure I had the right amount of resin in each batch for my small job I went to a Bed, Bath, and Beyond and bought a glass drink-mixing jigger glass and a small glass measuring cup. I never needed more than eight ounces of resin, and the cup was usually perfect. To measure the hardener for small jobs your only option is to patiently squeeze and count the drops one by one. It doesn't take that long. I mixed the two parts in old jelly jars I had cleaned and dried. Some plastic cups (including the red Solo cups I tried) will dissolve if you mix the fiberglass in them, but real glass won't. (4) Use very sharp scissors to cut the cloth; give yourself a large clear work surface; and ensure adequate ventilation. (5) If you want to buy more of the cloth in the kit, remember to order fiberglass cloth and not fiberglass mat, which is different and harder to work with. (6) Acetone is a superior clean-up material for this job, but it is very flammable, and it can react badly with some other chemicals. (7) Clean up very carefully, especially the fibers. I used a vacuum with a HEPA filtration system. It takes a little preparation to do it right, but it was fun, and the object I repaired is now stronger and much more rust resistant.

Small kit containing 1 can of resin, fiberglass mat, a small mixing tray which fits the top of the resin can, a wooden mixing stick, and 1 plastic smoothing tool.

Used it repair an leak in an acrylic tub. Repair has lasted a year and a half now, and still going strong. Tub repair company's repair lasted only 2 months.

Works great.

I like that the hole I made in my rv is now gone. This was a very messy process, no matter what I did to be careful with the resins I still got it on everything. The final result was very smooth, all I need to do is paint the spot.
