3M Semi-Rigid Plastic Repair, 04240, 200 mL Cartridge

I bought this o fix a foot long crack in my poly-urethane aftermarket bumper. I did not want to spend the money on the airless plastic welder so I bought this instead. I scuffed up the crack and applied the mix on the front and back of the crack then let it dry for a while. I twisted the area of the bumper where the crack is and the repair held up really good. The only downside and the reason for a 4 star is that the you get 2 mixing nozzles with it and if you need extra ones ( which you will if you don't use it all in one repair ) they can get expensive. The second thing is if you don't use all of it a lot gets left in the mixing nozzle which hardens and is wasted since you have to use a new nozzle the next time. Overall I'm pretty satisfied but I would have just gotten the airless welder if I knew about the nozzles.
