Then there is some other guy that uses only 1 layer on the rim, 1 on the tire...letting those two dry completely, and then gluing it the 3rd time. 1 day to dry.

This works great for a new, or super clean aluminum rim. Next time you mount the tire, probably on the side of the road far from home,you can use the existing glue if its tacky to the touch.Remember: The more glue you use, the more often you will need to clean the rim back to bare metal.
