I usually use the tool for unsnapping, but it may well work for snapping. I also put wax on the male part of the snap, to make it easier. A little on the ring of the female also helps. Starbrite makes a cleaner/ lubricant for snaps and zippers. Super Lube also works well, both have some teflon in them. There are several waxes in lipstick type of containers for the snaps.
