    Had a crack in the tub in a rental and was able to repair it for a fraction of the cost of a new tub. Acrylic bath paint after it cured for a day and it looks good

    4.0 out of 5 stars This product works great under stress
    Reviewed in the United States on September 26, 2022
    Size: 1 Count (Pack of 1)Verified Purchase
    I had used this resin product for my aftermarket bumpers. This product works great at patching any sort of holes, even small pin sized holes. One takeaway from this product is how well it works when a considerate amount of stress is applied. Since my aftermarket bumper doesn't quite fit with the contours of my car, I had to apply a considerate amount of pressure so that it would fit. Unfortunately, the stress applied was too much on my bumper and it cracked near the headlight area. But I used the resin to repair and fix those cracks. However, I coated the area 3 times so that it hold more strength and won't crack at that stress point, which it didn't. One thing that I didn't like about the product is how messy it is to use the product. Not only the resin, but cutting up the mesh cloth that was included in the box. Overall, this product works great for my intended purpose and I'm happy with the results.

    I took the chance and used it to repair cracks on my hard-shell luggage. I'm happy with the results after two overseas trips and rough handling by our local airlines. The repair has held on, and the integrity of the bond did not fail. It's well worth the purchase.

    I previously used epoxy to try and fix a crack in a tub/shower enclosure, but it cracked again. This time I put several layers of the fiberglass and resin down first, let it harden, sanded it, and then added some colored epoxy. So far, so good!

    The product arrived with a small amount of resin leaking on the outside of the box. when It was opened there was a large amount of resin that had contaminated the cloth. Since it was beyond the return date I will use what I can recover and throw the balance away.
