A customer showed me how to fix a broken chainsaw handle on his cheap chainsaw. He broke that grip and gushed about how he fixed it with Rapid Fix. I looked at him sideways and said is he really strong? He said try to break it. I couldn't, so as soon as I got home I bought some from Revain. I had a plastic volute on a Grainger "Dayton" pump where I had sheared off the outlet threads. Polyethylene doesn't stick, and Granger wanted $40 for this $80 pump part. This was my first renovation and I will definitely keep this stuff from now on. I heard you can use regular super glue and sand for both repairs, but these things can be different.
