Flex It 70

This stuff is perfect for my toy molds. Strong but flexible. Takes color great. The quick cure time lets me move fast through my workflow. This has become my go-to urethane resin.

Flex-It 70

As a first-time user, I did not know what to expect. I needed to cast some new tires on the wheels for my home woodworking shop power feeder. I found it exciting to learn a new to me process. The results are spectacular!! The new tires are soft enough, grippy enough, and very tough.

My favorite resin

It's firm, but flexible with a great feel in the hands. The 1:1 mix ratio is very forgiving if you're slightly off. Takes dyes like a pro and the cure time is great if you're not using too complicated of a mold.
