Should work OK for tires with looser bead, might be harder w/tight tires. I tend to use tire liners so flats are rare enough it's hardly worth the trouble to patch. & I rode with Schwalbe Marathons w/o tire liners for a couple of years with no flats IIRC. Spent big $$ in the old days replacing punctured tubulars. Tried to patch a Clement once & the base tape was stuck on but good. Some people had cottage businesses repairing tubulars by mail.
