I use sanding sponge pads, cut in half. Seems the older they get the better they get. More pliable for ornate furniture or in this case doors.
8 footers heavily carved on both sides. Stripped and clear water base exterior finish lacquer finish. 5 coats , self priming. 5th coat still looks a little milky BECAUSE IT"S WET !
Added the finished doors, now all I need to do is go out in the heat and hang them.
