System Three Resin Epoxies

Gel Magic Is pretty good... if you have time for it. A great addition to the toolbox

Gel Magic is almost completely non-sagging and makes GREAT fillets... and does so at a GREAT price point! Measuring it out of the containers is not easy though, and can take time. It is easy to mix and the color change makes it easy to know when you have mixed completely. The pot time allows you to get a lot of work done, but... The cure time is FOUR days. So if you want to keep working on a project, you really need to plan your operations so as to not inadvertently stress uncured joints.
