I agree, but the rubber cement actually helps as a lubricant to insert the “bacon rind” plugs with less effort. I’ve used them on car and bike tires, and though eventually I’ll stop in and get the tire dismounted for a plug/patch repair w/spin balance, they sure keep you from walking home. Had to stuff 3-4 bacon rind ones into an actual cut from a piece of metal into an almost new rear 180 tire on my old CBR1000F but it got me the 80 or so miles back home on a Sunday afternoon. Took all 3 cartridges from the kit to get the tire full enough to limp the shoulder to a gas station with an air pump, but a great outcome overall. Just another useful tool, to be used or not, I guess.
