An easy to use bonding product for woodworkers where strength and water resistance are required.
Excellent product. Easy to use. Pot time at 60 - 65 degrees was 30+ minutes with working time near an hour. Mixed product has low viscosity and gells slowly. It adhears to surfaces better and runs less if you are patient and allow time to gell. I am using the product to bond a large wood project. The metering pumps are a must have and make mixing totally fool proof. West Systems has a great web site and lots of information on how to use. Also several You Tube videos on using the product. Product can be stored with the pumps in the original containers for an extended time so minimal clean up.

Excellent Epoxy
This is some awesome epoxy. The containers come with a pump spout that dispenses the exact amount needed for perfect mixing. Super strong when dry. Allow 24 hours.

Absolutely the best.
The best part is the pump system, so easy to use, No scale needed. This stuff dries like absolute glass, and cleans up with rubbing alcohol before drying of course. It runs into wherever you need it to being pretty thin. There is almost no smell at all. I used this in a confined space with minimal ventilation, no mask and had zero issue with smell as well as my family who were Present when I used it. I used this epoxy to wet out the carbon/Kevlar inlay and fill the tip in my rc boat hull. This is amazing stuff, I don’t think I’ll be using any other epoxy for structural projects. My first choice seems to be a fantastic one. Working time is perfect for what I did with it. Around a 90 minute work time on surfaces with a thin film or 35-45 minutes in the pot. Soooo worth it. If I make a mold/boat I’ll be using this stuff without a doubt.

Excellent results for exterior gate.
Used to glue together a new gate made of cedar and will be exposed to the elements. Easy to use. Viscosity is somewhat thicker than Titebond but still very easy to spread with a disposable glue brush. Easy to sand away the drips. Open time was 20+ minutes using the slow setting hardener which was essential as this was a somewhat complicated glue-up. I love the pumps that measure the correct amount of each. I expect this will be my new primary glue for exterior work.

Excellent epoxy resin for fiberglass repairs
This is excellent resin. No odor. Great working time. Cures solid and tough but also sands easily. Highly recommend it.

The slow hardener doesn’t keep it super fluid for long
Works well once cured. I wish it was less viscous for a longer time. My specific application required pushing through an applicator, which was challenging.

Not cheap, but easy to use and super durable
It's hard to beat two part cured epoxies for durability and toughness, but they can be a giant pain to use. Get the ratio wrong, and you either create a solid block of resin before you get a chance to use the stuff, or a tacky mess that never quite cures properly. The dosing pumps that come with the two parts of this stuff make it easy and clean to get the ratio right so you can plan ahead with enough time to get the coating job done right. Although this is the 'slow' setting version, you definitely want to use it promptly after mixing, particularly if you're going to apply it with a brush (you want it liquid enough to level a bit before setting). It sets up nicely into a very tough, hard coating. You can sand it if needed, but it you do it right, you probably won't have to. It's not the cheapest coating you will find, but if you need the best, this is probably it.
