Review on 🔧 WISPAUSU Plastic Welding Kit: 800PCS Staples, 5-Levels Power, LED Display Light - 110V Car Bumper Hot Stapler Gun Plastic Welder Machine by Andrew Aldana

So a very simple concept. This sends electricity through the clip, which heats up and fuses with the plastic. This worked pretty well to fix a crack in one of the fender flares on my Jeep Liberty (it's too far to actually replace, I only used it for testing). You have to be careful because you will push the hot clamp straight through. He also has a crack-filling tool, but it's far from perfect. This works well for repairing a crack in the structure, but cosmetically if you want it to look factory like you should also consider other steps to finish filling it to make it look OEM. There are several options. Duraglass works well in small quantities for urethane bumpers. You can also use a two part automotive grade urethane adhesive/filler (works almost like epoxy). But you will always have a crack to fill when you want to prime and paint a piece. At least if you want it to look right. As you insert the staples and cut flush with the side cutters, also note the tiny, sharp pieces that are still sticking out. You can cut yourself if you run your hand over it. This is a good set, well suited to start a renovation. I'm glad it's part of my tool box. Urethane bumper repairs are happening at an alarming rate.
