Interesting tip about using talc. I have used it as a lubricant when threading cables into conduits but using it with abrasive paper is a new one on me. I have often used W&D with water to rub down cellulose spray paint and oil paint, in the latter case leaving several days between coats to ensure thorough drying, but the paper does need regular cleaning: I use a fine brass wire brush, but it never gets it all off. Must try talc next time.
