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.

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.

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.

great epoxy
I bought this for an outdoor furniture project. The mini pumps make mixing a breeze. It has a very low viscosity without fillers. I used it for sealing and laminating. Requires a filler to increase the viscosity for general bonding. Excellent adhesion and easy to clean up after curing. I used the 206 slow set hardener since my project required many joints. The pot life was about 20 minutes so I was able assemble 20 joints without panicing. Can be used for many applications depending on the type of filer.

Great product kit that’s easy to work with!
This was great. Pumps were great, good instructions. Used this to fill in some gap in a slab of cherry wood. Everything worked perfect. I sand down the unavoidable excess with a random orbital. It all worked well and was very easy with the pump measure system. Since it’s winter now make sure you bring your epoxy inside overnight so it gets up to a normal temp otherwise cloudiness could occur if you are going with a no tint clear. I used powdered charcoal off some old embers from the fireplace and separately mixed a batch with the wood powder left from sanding. Couldn’t have been more pleased. The packaging left things loose, that’s my only complaint.

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.

Great product. Easy and accurate to use.
I've only used for one project so far. Gluing a 45 degree cut for a wooden waterfall vanity top. The ease of use with the pumps is a game changer. The extended open time for my woodworking use makes glue ups less stressful. Due to more consistent hardening I also find it much easier to clean up squeeze out. Just wait until it becomes semi-hard and the clean up is easy with a sharp chisel.

Great Epoxy
Worked great on my rv slide out. Cured clean and hard in about 24 hours.
