Like everyone else says. I also only use the Rema patches. On the road I wait about 5 min for the "glue" to dry. I have a set of those plastic "sport" levers and use one of the levers with the red "holder" as a backing to press down on the patch after applying it. At home I let the glue sit for half an hour or more while doing something else. Someone suggested using one of those tools for rolling in screen splines; I had one in my toolbox and I started using that at home, really going over the applied patch in different directions (in particular along the mold seam) and that seems to really get the patch on tight. I've never bothered removing the "cellophane" plastic on the top of the patch.

Note that the Rema patches have 2 versions like Touring TT01 and TT02. One (forget which) has more of the round patches. I've never had a need for the oblong patches on road tubes. I probably have twenty of them in one of the Rema green boxes left over.
