Easy to use
Easy to use, great results, as long as you use precise matching volume of both A & B. Called tech support to check temp. required. Needs to be above 65 degrees but not over 90 degrees. Below 65 will slow rising action but not overall ultimate rise according to them. Worked great.

I use this to reinforce the "fin can" of high power rockets, and it is very easy to use and so much more economical than buying small quantities from rocketry vendors.
