I used to, but I don't anymore, and haven't for a few years, with no failures. All I do now is run the board through my thickness sander, or across the belt sander with an 80 grit, and it gives me a nice clean, flat, ready to glue surface. I make sure the board is free of dust. I vaccum it with the shop vac, and then blow it off with my compressor. I use TB3, so no toothing plane for me. I also used to do that too, but also no more.
