How often (if at all) do y'all sand your scratch box rails and/or the striker?
If so, what grit sandpaper do you use? With vs. against the grain?
Greg Longuillo (L&L) recommends 220 grit, Richard Shively (Super Yelper) recommends 80/100 grit, so not even the experienced call makers are on the same page!
Any input is greatly appreciated, thanks!
