Bondline reusable vac bag system

Has anyone used their set up?

Do you know if they sell just the vacuum bag film. I believe it is silicone.

I have a couple molds as of right now that i would love to make into reusable bondline style. It would save much $ and time.

Also if resin cures on the bondline bag film material does it just peel right off?

I currently use Stretchlon 800 vac bag and it is stretchy without tearing, but my feeling it it is not stretchy enough like this Bondline stuff.
