Dear Ed: Roughing up the wood surface isn't a good practice. Coarse grain sandpaper will "fray" the wood fibers and will weaken your surfaces to be glued. The best is obtain a surface as smooth as possible using fine grain sandpaper or a plane. Clean the surfaces by means of a piece of cloth using thiner, absolute alcohol or nails varnish remover. After dry (only a few minutes), put the resin trying to do a good impregnation so as the resin can penetrate the surfaces. After that put some excess of resin and clamp.
