Thanks for comments, yes, this makes sense.

I wonder if having a dremel handy in the shop might make the "abrading" step easier and more reliable. I try and do a good job with the little piece of sandpaper in the kit, but it is difficult to really get a nice uniform abrade across the entire surface of the patch. (In the field, I typically just use a new tube so as long as I don't get two flats in a ride, I don't worry much about field patching.)

Old-timers wil remember a kit called "Match Patch" in which you clamped a patch assembly onto the tube and then lit it on fire to fuse a patch onto the tube. You never worried about a patch leaking with these things!
