I'm using plywood for part of a project, and the edges are fine, since they're being covered by trim. However, there are some spots on the plywood that are rougher, have nicks and scratches, etc in them. I was googling around tonight and everywhere is saying you should never really SAND plywood. Like it should be this silky smooth loveliness already. Mine is fairly nice in a lot of spots, but there are a few trouble areas. Do you sand plywood? Do you just use a TON of wood filler on those areas and then sand those down?
It's going to be painted, so I'm not concerned about the colour differences with wood filler, but I AM concerned about having a smooth finish ;)
