Review on System Three 0102K46 General Hardener by Bill Russett

I like System 3 epoxy. The 2:1 ratio is easy to use for small quantities. I buy a tin of medicine measuring cups in the pharmacy and use them to measure the two components, pour the result into a clean cat food jar, mix it up, done. Medicinal cups are very cheap by the hundreds, so I throw them away at the end of the job. I find this system much more reliable than West Systems epoxy pumps. If (if) any of these pumps inject air, you have no idea how much resin or hardener to add to get the right 5:1 ratio.
