David,

How much clamping force is required with the gorilla glue method? Would my car battery method (clamping the foam blanks together) work, or do I need more weight than that?

Also, do you roll it on?

The stab is already done with sourghum, so if anyone knows the answer to the question about glassing and painting over a skin bonded with it, I would be interested to know (ie, will it be ok to glass and paint a wing bonded with Southern's Sourghum?).
