Ask the dock Manager if he has any styrafoam blocks he wants to get rid of ......... I understand it is a bit of a nuisance for the store to try to send them back or to dispose of them .

I had considered using the Nail Glue adhesive but ........... when I shoot out a block with my setup , I can loosen the straps , replace a block and tighten the straps back up . Can't do that if they are glued .
