Re: How to build good bumpers

My personal (empirical) experience is that the better grades of plywood do hold fasteners (staples, nails, screws) better. I also find it nicer to work with since it splinters much less when cut. For the ultimate, use Baltic birch like MrRoboSteve.
In that case it isn't a few bucks more. Cheap S2S plywood is still just standard 5 ply only smooth. From what it sounds like you are describing, it would be almost double the cost.

In my opinion, bumpers are a waste of Baltic birch plywood. Utilitarian items don't need furniture grade material when sheathing does just fine.
