should have done this years ago
I've been struggling with a cracked pool step for a few years. I've used two step epoxy sticks and flextape, and other quick fixes. I finally got fed up when the step developed a new crack. this stuff is awesome. I applied white pigment for epoxy before I added the hardener to the epoxy and stirred well. I added the hardener as stated in the directions. I also used this 3m bondo fiberglass cloth just to give extra trength because the step seems hollow underneath and dips in the middle. worked out great. the directions state it has a 12 minute work time after the hardener is added. poured well and covers easily with a cheap paint brush. it hardened in just an hour. cure time is 2 hours. the key is to stir for several minutes after the hardener is added. don't be lazy in this step. it has to thoroughly be mixed, paying close attention to get the bottom of the container you use to mix it in. if you don't, the stuff on the bottom, after you pour, will be on top after pouring and will be tacky and not cure properly if you don't mix it thoroughly. i am very pleased. it's easy to use. i cut this to size, poured a thin layer of epoxy, then laid the cloth. i poured another thin layer of epoxy over it and brushed the epoxy into the cloth, saturating it and removing air pockets. then i poured the rest of the epoxy to cover the whole project. the step is strong and waterproof now. all cracks have been fixed and reinforced by this cloth and epoxy.

Works as it should. Cut carefully with sharp siccors, it freighs out, gets a little stringy.

Good fair price
Great fiberglass cloth good quality big 8 ft cloth that covers a big surface 👌 or makes a really thick smaller surface area with layers I tend to double layer these cloths or sometimes triple layer for a stronger strength this stuff works great with proper installation

Strong & Reliable, But Can Be Messy
Strong & Reliable, But Can Be Messy I’ve used Bondo Fiberglass Cloth for various repairs, and overall, it’s a solid product that gets the job done. It provides great reinforcement when paired with Bondo Fiberglass Resin, making it ideal for automotive, boat, and household repairs. Pros: ✅ Durable & Strong – Adds excellent reinforcement to repairs. ✅ Versatile – Works on metal, fiberglass, wood, and more. ✅ Waterproof & Paintable – Holds up well in outdoor conditions. Cons: ❌ Frays Easily – Cutting it can be messy, with loose strands everywhere. ❌ Requires Careful Application – Can be tricky to work with, especially for beginners. Overall, it’s a great fiberglass cloth for structural repairs, but be prepared for some mess when handling it. If you need strong reinforcement, this is a solid choice

A bit misleading…
This is fiberglass fabric and it worked well in my application; fabric & epoxy coat of a home built battery box. However, please note… this is NOT A PACK OF 6. At the time I purchased it, it says Pack of 6. Baloney! It’s a pack of 1 (approx 8 sq ft).

This fiberglass mat works as expected. It's my first time doing any fiberglass work, but I'm learning and improving the more I do it. I am using a double layer of this matting to rebuild the rear fenders on my van and it's doing the job....slowly due to me being a newbie at this stuff. It appears that it's best to use smaller pieces to cover the area and build up several layers over time. I still have to figure out how to bend it around sharp corners but that is probably an issue with any fiberglass mat.
