This epoxy is easy to mix and apply, but keep two things in mind - it's a bit thick, so wetting out glass cloth (don't use strand mat unless it's specifically epoxy rated) can be a bit tricky, and they aren't kidding when they say the working time is 5 minutes. This stuff is great for patches and crack filling (I used it to repair a bathtub that had been damaged in shipping) but I wouldn't recommend it for laying up any items of large size due to it's fast cure time. My rough guess would be no more than a 1' square patch with 3 layers of glass - and have plenty of spreaders handy. My preferred way to laminate a patch using quick cure resin is to precut the glass, set the pieces on some visqueen, pour the resin on the cloth, spread it, lay another layer of visqueen over the wet glass, and then spread with more pressure. As soon as it's wetted out, peel the patch with the top layer of visqueen off your work area, and slap it onto the area needing repair. Note: you may want to slightly prewet the patch area with resin, especially if it's textured or rough Work out all the air bubbles (quickly, you're on the resin kickoff clock!), let it cure, and then peel off the visqueen. Keep in mind that the strongest laminate will have only enough resin in it to wet out the fiberglass completely, but in a repair situation, this epoxy seems to do a good job of filling the voids, and appears to be strong even without glass fibers infused into it.

This epoxy worked very well for my first small project. However, when I went to use it again, recently, the resin was hard (most of the bottle). I purchased this January 2025. It is November 2025 now. I am surprised that the shelf life is so low ... less than one year ... unless I just got a bad batch. Again; when I used it the first time, it was easy to work with and is still strong and durable on the parts I repaired. I don't know if I want to buy this again. R.J.T.

According to google this is the strongest adhesive to use on a boat. I repaired some stringers, didn’t seem necessary to replace the whole thing. Cut out the bad places, made patterns from cardboard and then patches from wood. I got the product out of the bottle by removing the caps and squeezing out dollops. It was a bit thin for this use and ran out of the cracks. I thickened it with some silica. Put part B in a container, added silica until a little too thick then added part A. Mix it well and hurry ! Stayed put better with a little help until it starts to set which isn’t long. Will cover with fiberglass.

Worked very well on a cracked boat hatch lid

I use this on my rc boats. Very strong and holds well. Haven't had anything fail on me using this. Wish it was a bit thicker but I let it sit for a few minutes before applying which helps.

A woodworker said to use marine epoxy but this is way too thick for that. It's a royal pain to deal with and doesn't dry clear. Avoid it for slab projects. I should have used "casting resin" that is pourable. This was almost a complete waste of time and money for the intended use case. On the other hand it bonded really well and the polyurethane had no issues coating it but never use it for woodworking in my opinion. The project came out okay but I would never use this again for that purpose, it's almost useless on smaller cracks. I gave the unused portion away. It's not that much different from JB Weld or something like that. Also it's very hard to get out of the bottle in any quantity. Use a small drill bit to open the spout a little bit before trying to get much out.

This work so good, follow instruction apply in warmer weather of use a heat gun or hair dryer to warm the surface being repaired. I went a little crazy and put on six coats inside and outside of a hot tub shell with hair line great that lost 1/2 the water level every two days. It’s now been holding no leak for two weeks. 🙏🙏🙏🙏🙏
