Hi,

We had a similar problem on our LR White resin sections. Have you tried leaving
the slides to cool for a couple of hours after they have been removed from the
oven? this seemed to solve the problem for us. Also what type of plastic
wrapping do you use? we found that saran wrap seemed to work fine whereas using
a thicker plastic wrap caused problems when we tried to remove it.

Hope that helps

Matt
