Does anyone see problems with what I am about to do here? I would prefer using 1 1/2 to 2 inch foam but all that is easily obtained down here is the 3/4 stuff. Any suggestions on what glue to use to bond them? Maybe a spray adhesive so I get 100% coverage instead of the liquid nails stuff? Also, any comments on using 1/4" thick "pegboard" material under the foam?
