Today I cut and mitered 22 pieces of No-Rez for a SEAS A26 build with Baltic Birch.
Question #1: Apart from making the wood surface free of dust and particulate, is any surface treatment like primer beneficial here to make sure the No-Rez sticks for decades? I used No-Rez twice before on MDF, one primed and one not, and it worked out great.
Question #2: Normally I cut the foam part back 1" from the baffle and leave the damping for that 1". Would a 45 degree angle do just as well?
BTW, Bosch jigsaw with wood blades worked great but took a few blades due to the rapid dulling caused by the damping layer.
Another tip - the free program Cutlist 4.04 is invaluable for laying out sheet goods and also No-Rez to minimize waste!!
