3M Fast-tak is good. The reputation that it causes the base tape to separate is that often upon removal the base tape is bonded to the rim more effectively than the tire. Be sure to use the #8031, not #8001. the 001 stuff dries brittle.
The Vittoria glue is the best current stuff I have found for road use as it will retack a spare whearas Fast-tak will not. Of course the old Clement Gutta, the red stuff, was great, but it is long gone now. NOS stuff that shows up on ebay is too old for me to trust.
