Excellent product, performs exactly as described.
This is the best epoxy repair available. You need to clean the repair thoroughly. This has a long pot life and slow cure which makes for a more flexible repair. I've repaired boats and surfboards all my life. I've also done automotive part fabrication and repairs. This time I repaired a ceramic basin for a fountain. I cleaned and opened the crack. I used fiberglass chop into the fissure. I then overlaid fiberglass cloth over the entire bottom of the basin. Then I poured the epoxy mixture onto the repair area and used a plastic putty knife to work the epoxy in and the bubbles out. Last I vacuum bagged the repair to drive the epoxy deep into the fissure. Your have plenty of time to work with this product so don't rush. Make sure to thoroughly mix the two parts (epoxy and hardener) in equal parts, but don't mix so fast that you create bubbles in the mixture. I probably worked the repair for 15-20 minutes to get to where I wanted things When your finished, leave the repaired object alone for at least 24 hours to harden. After reading some reviews I was worried it may be sticky, it wasn't! The fountain basin is holding well with no leaks detected after several weeks. Don't use this product if you need a quick dry time!

Great product! Very impressed!
This epoxy went above my expectations! Bonding mdf and stainless steel (building a router table). Plenty of working/adjustment time, and a pretty fast cure time! I tried others such as highly rated two ton epoxy (that delaminated in places and separated easily under mild heat). West systems 650 is holding up to mild heat, heavy vibration, pressure, and friction so far. Definitely will restock with a bigger supply when I run out, for any future needs.

Pool filter fixed!
After the bottom of my pool filter cracked all the way across I was dreading buying a new one. Not to mention the one I have is only 4 years old and discontinued. Found a reddit post about how good this stuff works and man was I impressed. Saved pool season for us and is holding up great?

Great stuff.
This stuff can handle the load. I use HDPE blocks on my boat, I don't like to holes in my jon boat. It adheres the two materials great, I use it for my pole holders plus my fish finder. I can grab the pole holder to stress it an you can see the hull flex slightly. One tip it has a 45 working time this stuff is runny depending on temp. let it set for a few mins. with in the working time and you will have better luck to stop any runs. Ask me how I know. Play with it in small amounts to see what works best for you on vertical surfaces.

Very liquidy
Very liquidity runs all over . For wood and clamping it properly would be a better option. I was using it on an outdoor statue. Very long working time. This stuff is amazing. Once’s it cures it is never going anywhere!!!

Works well, long pot time, waterproof, clear,
Excellent epoxy for niche projects like building custom knives which I engage in frequently. No color, very clear, will take expoxy stain, waterproof, Food safe, a little thinner than I would like. Drying time is fairly long but the tensile strength is really good. My one star deduction is for the price and the containers. This product has gotten very expensive and the containers are really annoying to dispense accurate proportions of the resin and epoxy. A large twin syringe with a push handle would solve the mixing issue. The price increase would be warranted with an improved dispensing system

Worked perfectly for me
I used on a plastic canoe. Do your research to make sure what type of epoxy or resin that you need to use on what type of material Your Vessel is made out of. In this case this specific chemical compound with the chemicals that made up the plastic canoe that I was using work perfectly together for me to adhere a strike plate with felt using this epoxy

Works on Guitars!
Used it to fix (rebridge) my poor and abused acoustic guitar. I figured if it can hold a boat together and not give in to moisture, it’ll probably work pretty well for my guitar whose bridge (the little piece of wood that holds the strings under the sound hole) keeps lifting and pulling away from the body (needless to say the rest of the guitar). Easy to apply and it cures quickly and very thoroughly. Unsurprisingly this is the ONLY glue that has worked for my guitar so far, and that’s because it’s epoxy and not glue! It’s been a journey and I’m glad it’s finally over and a working solution has been found. For those who are curious or looking to do something similar: I previously tried Titebond trim glue (it’s what I had) which failed spectacularly and pulled off beautifully like fresh melted cheese on a pizza (which was NOT the desired outcome), then I tried Titebond original two times since people claimed it would work fine (it doesn’t, I live in south Texas), and after throwing away my old proprietary bridge and buying a new one and struggling for a few hours I finally used this and it works great! Only took about two teaspoons total (one of the clear and one of the orange). It was easy to spread and the perfect thickness and I haven’t had to worry about my guitar bridge coming off at all since.
