If you ever acquire a print dryer with a glazing plate, the solution will be handy. If the Johnson stuff is the same stuff as I've seen listed elsewhere, one normally wipes a thin coat on to the glazing plate and then polish it off. A damp FB is then squeegeed on to the plate and then left on the dryer at a fairly high heat setting until it pops off. This gives the print a final high gloss finish if done correctly (I'm still working on that part).
The stuff I'm thinking of is typically a mix of beeswax in Turpentine - If the Johnsons has a turps smell about it, you don't really want to be putting it down the drain.
