Hi Warren,

It's the 'Shore A' scale I am referring too. Car tyres are about 70 Shore A, our flexible epoxy is 80 (well, 79 to 81). It actually feels reasonably flexible, especially when it's only thin. As you would expect, when you get to something more like a solid block of the material then it feels considerably harder but it's only perception. Shapes like the bushes workaholic_ro is making would feel pretty hard because of their shape. I believe the EF80 to be a really interest balance between a rigid material and a fully flexible material - you could certainly make a front bumper out of it and it would hold its shape without deforming or sagging and yet it would withstand a huge amount of abuse (I'm thinking rally car use).

All the best, Matt
