Maaan this stuff is a tecnological breakthru, it will save me a good bit of materials cost. The only downside I can see is its only good for maxed out patterns that need no work.
The two part stuff I buy makes stuff that can be sanded and added to with polyester glazing putty to mod-finish up.
This stuff ,you cant do that - but damn, reusable!!

Whats the working time when you pull the blob out of the water?
