I've just recently started working on my first project making poppers out of cedar. I turned them on the lathe, drilled all of the holes, and dipped them in 3 coats of poly. I realize that you're supposed to sand between coats, but I didn't. Luckily, I didn't have any problems. My next step is to spray with Rustoleum painter's touch ultra cover 2x primer.
My question now is what kind of sandpaper does everyone use during the process? Does it matter what I use at this step since I'm going to prime it? Will something like 220 grit work? Or should I go to the microgrits and use something like 400 or 500?
Thanks for your help,
Stephen
