3M EZ Sand Multi Purpose Repair Material, 05887, Ready-To-Use, Two-Part Epoxy Finishing Adhesive, 200 mL/6.75 fl oz Cartridge

Used to repair a bumper on 92 mustang gt that was badly pitted and stress cracked. This worked great, I can’t imagine anything working better. I didn’t use a mixing gun, just pushed out equal parts of each side and mixed. I ground out the areas. Once dried sanded easily with 180. Remained flexible, sanded and painted well.

This stuff is so amazing, and it can fix more than just bumpers. I had a large fiberglass spoiler that had gotten cracked in shipping. I worked this repair goo into the crack, sanded and repainted and the repair is invisible and has held up over a year with no problems. I've fabricated missing mounting attachment points as well, just spread a puddle of this along the section and cut to fit when it cures. I had acquired a used polyurethane underbody spoiler with numerous cracks and rips and was able to restore it to almost perfect condition, despite having sections where the plastic was completely missing -- it's now ready for paint. While it's expensive, I cannot believe how well this stuff works, it's easy to work with, has a relatively fast cure time and is very easy to sand for a seamless look. I wish they sold smaller quantities, this 5oz kit goes a LONG way.

I use this since the 80’ s works great , is a little pricy but it fixes and fills scratches on plastic bumpers great . I used it to rebuild a mustang nose went back together great! Mix equal parts “ black &white “ on a plastic or cardboard piece until it is thourally mixed apply to a clean sanded piece and 30-40 minutes later you are sanding to a paintable finish . Drill out stripped out license plate holes and fill , let set 40 minutes then redrill to correct size. Works great.

I used this product on the front of a bumper repair. It mixes well, covers well, and sands amazingly well. Follow directions and USE adhesion promoter spray and the edges feather nicely. And can literally be sanded to 180 grit in 20 mins. Spend the extra $20.

Sticks super well and is sandable so you can level a bumper repair with this and then prime and paint the repair without worrying if it will fall out

Excellent strength; however, the material is black. In its uncured state, the black portion can ooze and make a very difficult mess. This is a larger system than typical 50ml cartridges and so is well suited to larger jobs.

Used this to fill in some gaps in an ABS front lip that was customized to fit properly. The tip mixes the two parts perfectly, and the product spreads easily. Dried to be able to sand in the exact time mentioned in the instructions, then dried to an extremely hard and durable final product after letting to cure overnight. Took off one star only because it is described as having adhesive properties but it does not seem to adhere very well directly to flat edges, however where it was feathered out through sanding it does appear to have adhered enough for an acceptable finish.

This item is used to bond plastic like if you’re fixing a crack bumper it’s a great for repairing vehicles if you know what you doing
