I have used glue less patches for several years with about a 98% success rate. Who wants to wait for that stuff to dry when it is 40 degrees out? I guess that is when you swap out a tube, but I would rather just put the patch on and get on with my life. I will say that the glue less patches are not as good in the situation when you have one or thirty on a tube, and you need to fill the tube up outside the tie to find a leak. They don't stretch well so at that time it is time for another tube. Another $5 down the drain . . . .
