Interesting subject, I didnt even know what casing was before i joined this forum,
ofcourse i was wetting my leather dont get me wrong but it all seems a bit to mutch like rocket science to me or a good way to make money selling a product that you dont really need,
ive been doing for years basically the same thing when i want to carve or stamp, i hold the leather under running water for a few mins then set it aside for a couple of hours till its nearly dry and cold to touch, no soaps chemicals or mouthwash,(LOL)
although im going to give the spray bottle a try out and see if it works for me, Don
