Do tubes need massage before mounting? Maybe. my experience with sealers is confined to nashabar's and Woolmorts-the old wools, the new ones appear to be Slimes and well fed. but as i have six nashbar's, that'll wait. this developed commuting. as each tube absorbed glass shard and holes, i'd retire it to the wall and mount a new one. tus the six walled. yesterday, (having run out of fresh tubes) i repaired 3, threw out 2, and kept 3 more on the wall. what gives here is that Nashabr's have fibers in the solution, the fibers working to the puncture and then sealing the hole as the fibers make an escape from tube pressure. some self sealers show fibers blocking the holes, some do not. the tubes showing fibers are vastly more effective at retaining pressure than the tubes not showing fibers at the holes. massage the tubes b4 mounting!!!
off course , it might be that some tubes have fiobers and some do not but that's a lot like the paranoid idea that your tire in not going on the rim was defective and came out the wrong size-the upside down buffalo nickel theory.
also, keeping the puncture sealers in storage blocks the whole so well that dunking in the trough not only off ends the pigs but doesn't reveal any air bubbles. gotta letum soak b4 the solution softens. aha!
ok. the idea was' fibers clot in storage. like good rope in the dark or the electrical gubbins box filled with wire and leads. so the massage gets the fibers laid end to end the the centripital forces flatten the fibers out against the outer tube wall whilst running... unless there's an imperfection or eddy giving greater friction then: another clot. fiber lika hole seaking STP: ___ ___ <TUBE U
