Reply yeah, i was thinking cutting board, but liljohn says i can not glue to that. I am trying to get some backing on the inside wall in the passenger compartment and the wall actually has a little bit of a jog in it (where the walkway goes into the bow), so i will have to fir out part of it to make it flat. there is some sort of backing in there now, but it is not wide enough for one of my amps.
