This stuff works great - a little messy but really fixes tool handles
The lever on my recliner broke, and there does not seem to be a way to replace it. I used this repair tape to make it good as new. The wet tape is a little messy but other than that it works great. I have used it for tool handles as well, and they are as strong as new. Excellent product

Phenomenal
I'm actually shocked how well this worked. The entire pedal arm of my Elliptical machine cracked. It's 15+ years old, and just came apart at the weld between the pedal and the axle. I really didn't think this would work, but someone recommended I try it, and the part is impossible to replace 15 years later, so it was this or the whole machine goes in the landfill. I read the directions, and followed them perfectly, which it is clear from some of these reviews that not a lot of people did. I wrapped it, pulling and stretching it tight, and then wrapped it with the temporary bandage over top - it refused to stick because I had mistakenly gotten it a little wet with my wet hands. So I put a zip tie over the whole thing, and 5-7mins later, as per the directions, I removed both the zip tie and the bandage. I let it cure for a couple of hours before testing it on the Elliptical and to my shock and delight, it's good as new. It's held up great ever since, no sign of trouble. Thrilled to not have to replace an entire machine for thousands of dollars, thanks to this little wrap!!

Are you tired?
Be sure you're not tired when you use this product. I was exhausted but determined, and therefore forgot to use the outer wrap to seal. That's what creates a beautiful molded shape around the leak. Now the leak is concentrated and spewing like a geyser because it wasn't wrapped properly. Without a tight winding of the outer wrap, the inner wrap can't set snugly. The inner wrap also hardens to damn near impenetrable very quickly, so now I have to freeze it off with refrigerant because I 'd have to use a power saw to cut through the layers and no doubt straight through the PVC. J.B. Weld ain't kidding with the efficiency of this product. Just be sure you're well-rested and follow the instructions to the letter!

Repaied a fiberglass shovel handle.
Had a fiberglass handle shovel split at the pin, the shovel was useless, instead of throwing it out I thought I would give this a try. I am impressed at the ease of use and the rigidity of the cured product. Although, it may not be the pretty, the shovel is functional and ready for many years of use now.

Easy to use and great joint strength
Fiberglass is naturally messy and this helps manage the application of fiberglass mesh. Gloves included were sufficient, can’t believe water is the activator as MEKP is generally required. Helped reduce the odor. I allowed the product to dwell 2-3 minutes after exposing to water to essentially firm the resin for greater forming around a furniture leg. Essentially preventing the mesh from unravelling. I was able to sand/grind the fiberglass within 20minutes. Product is impressive.

Absolute garbage
Fiberweld acquired this product from Fiberfix a few years ago. The first year they just changed the dimensions. After that they drastically reduced the quality and strength of this item. What used to be a fairly solid wrapping, is now a horrendous sloppy mesh. Imagine making paper mache art in elementary school, layering sopping wet blobs of newspaper and glue onto an art project. This stuff is basically the same, and only a little stronger. The ends are frayed and strings unravel from them. It cant grip anything to save its life, and unravels as you wrap farther up whatever you're fixing. The old after-wrap plastic strip that used to be included was replaced with a sort of stretchy fabric. This fabric piece folds over on itself horribly, and the fiberglass part foams and bubbles up like that spray can insulation foam. That traps the fabric wrap. If you take it off before a certain time, the fiberweld loosens up, ruining your project with a weak bond. If you wait too long, it bonds to the fabric and you cant take it off and it's now permanently part of your project. There is no perfect inbetween time, it's one or the other. The gloves included are also horrible, too small and they break too easily. I'm not some novice at this product either, I've used it and its predecessor probably close to 100 times. Absolutely do not purchase this product unless Fiberweld discontinues it and brings back the old one. I ordered the automotive specific ones to give them a try, but last time I did that they sent me these ones instead and I returned them. The white one is a little better, it has all the same flaws but not to the extremity of this one.
