I've read about this spray before, but haven't found it. Has anyone in Canada been using a spray? Where do you find it? and the brand name? Please and Thanks!
LaLaLand ... you mentioned a silicone mat? How large? The one I saw at my LQS seemed pretty small, in perspective to what I thought would be workable.
Also, what really is mylar? Isn't that what those foil type helium balloons are made from?
