I've had trouble getting hold of this too. I have been told that it's something that every magician has around the house.
Glad I'm not alone! A Pritt Stick could possibly be a good alternative solution. I repaired a Rising Deck using this and it works fine with just another dab now and then to refresh it.
You can also use a product called Changin'Glue. Anthony Owen devoted a whole book to the stuff. You can get it a number of places online including: http://www.bicycletricks.co.uk
I was thinking about that last post and hope it doesn't look like a blatant plug (since I look after the bicycletricks site). But I don't run the site commercially - it is more of a personal service, originally designed to help magicians get hold of small quantities of gaff bicycle cards - and as such I am pretty sure that it is cheaper than any 'commercial' site I have found so far.
