I'm doing a test of this stuff combined with a polystyrene plug that I'm going to dissolve with acetone. I got a thin spot on this first try where I made the plug a bit too large, if this one doesn't work I'll try again with a smaller plug.

Even when I get one to hold a goal pressure of 60 psi inside my mold, I'm still concerned about getting the bladder out after carbon layup and cure.

I ordered Smooth-On's test batch ... for making inflation semi-bladders, instead of vac bags. For the parts I'm doing, vac bags are very inconvenient.

I don't have results to post yet, but of the small test patches I've played with, the finished silicone does indeed seem very durable.

I'm going to try this out soon... it indeed looks like a great technique to make more parts

Anyone tried this before?  Have a look for: EZ~Spray® Silicone 20
For those of us making multiple parts, it looks really good...

Would be good to hear of anyone using it, and if EC would recommend it?
