Plastic/acetone maybe a little = faster. It's only when you soak the hammer that the dry time increases. = With lacquer I find that in 2 hours you have 80-90% of what you are = going to get.

Susan On a hot day in the shop 80 degrees or more The lacquer solutions = will dryquickly enough so that that the sound is changed within an hour, = Except on the largest bass hammers that were really soaked this it takes = two hrs.

It changes a bit more overnight and breaks = down some as the next tuning gets pounded in. If it's still too edgy a = little acetone on the top will wash it in a bit and won't take long to = work with. If it's not enough repeat with another light application.
