Re: [ULF-1] Ulf-1 Digest, Vol 70, Issue 4
Hi, Just a point on sanding. Not recommended for the Member 60 surfaces, but an absolute must for plywood in order to remove the release agent that is generated in the manufacturing process from the surfaces to be glued otherwise there is a risk of failure. Give it a good brush after to remove the dust.
