Hi,
I did a mould using PU600 Density Polyurethane Model Board but end up having a mechanical lock when I tried to separate the mould from the board.
Apparently accetone can disolve  the polyurethane but  I was wandering if you guys have any advice?
cheers.

We always recommend ensuring you have a small draught angle to the near vertical edges.
