206 Slow Hardener
By Chuck from Jenkins Boat Works

Verified Purchase

Being summer, I really want the extra pot life time that this slower hardener allows. It also has little or no blush when cured and even as a slow hardener, usually set up to the touch in 12 hours

Bottom Line Yes, I would recommend to a friend

WebSite Picture Misleading - Caused Incorrect Order
By G Ag from Farmington, UT

I purchased online a gallon of West System 105. When I was making my online order I selected the web page for the 206 hardener . The web site came up with a picture of the 0.87 quart size of hardener next to which was the description (I didn't notice the description was for the "A" size) inadequate for the gallon of 105 I purchased. I didn't notice the error until the shipment arrived with a gallon of 105 and about one cup of 206. This mis-leading web sit photo caused an error that has delayed my project. The photo on the web site should match the description and change when you select a different size.

Bottom Line Yes, I would recommend to a friend

Even though it is winter, I still use the slow hardener. I just don't like to have my pot go off before I"ve used all that I mixed. This stuff is excellent.

West System is great
By Hutch from Plainfield, Vermont

Verified Purchase

I have been using West epoxy for decades. I have used it for sailboat maintenance, radio antennas, car bodywork, building repairs, toys to timbers. Anything that needs to be filled and faired. The ability to select a hardener for speedy hardening or extended working time is a great advantage. I have used soft filler to repair wooden items like the rotted frames of very large windows that I got free to install in the barn workshop. Once filled they are stronger than wood and impervious to weather for a long time. I have pumps that I occasionally use if I want perfect proportions. But I usually just slop some resin and hardener in approximate proportions into a mixing tray, and for mot purposes it works very nicely. The measurements would probably be more economical and perhaps produce a better finished product but for most jobs I don't bother. The pumps leak as temperature changes expand the pressure in the cans. A sturdy end cap on the pumps would help. I've tried electrical wire-nuts and they are marginally effective. The pumps are messy, and usually spend their time on essentially empty cans.

Bottom Line Yes, I would recommend to a friend

Good product
By Boatbuilder from Dubuque,Ia

Verified Purchase

Normally I prefer only Fast hardener, however, I had a rather large area of mat to wet out and anticipated warm weather ahead; so I purchased the Slow hardener. I did not realize the job would require so much resin and used up all the West System Resin that I had. My preference was to purchase Total Boat Resin because I've grown to like that product more than West; not to mention the money savings with free shipping for Total Boat. Instructions indicated I could use the two name brands together so I purchased Total Boat Resin and the West System slow hardener worked fine with the Total Boat Resin.

Bottom Line Yes, I would recommend to a friend
