I seem to have bad luck with sealing a vacuum bag with shipping tape. So, for my last bagging I used only Liquid Nails ($2 a tube). It was a small bag (32″ x 72″ part) so it only used one tube. The shipping tape costs more than that as I recall. My

plastic storm window splines all wore out and I have not gotten around to buying new ones. They are my favorites still. If I have them.
