finnishing up rails

What do you guy`s use to finnish up the rails … screen or regular sand paper ? Aloha , Cal

cal, i take boards to 150 grit if they are to be tinted. airbrush or clear, i go to 120 grit- you still want the paint and resin to do its thaing. some swear by the old screen that has been ‘broken in’ for a while.
