Vasek
I used Probond Polyurethane Glue for the foam sheeting. This week I had to remove some of the balsa covering for the flap well and the glue had bonded the sheet balsa to the foam as well as anything I have used. I realize that there are several glues using the probond name but I thought I had identified the Probond Polyurethane as the glue used to sheet the foam cores. Sorry for any confusion this may have caused. By the way, there are several threads that relate to covering foam cores using polyurethane glues.
