There are some very exotic chemistry in the specialized products.)
Right (people are presently more difficult!), and these are manufactured for more critical applications than bikes used for neighborhood riding, in which cheap patches usually work, and most flats are a result of bald tires (despite advising them not to skid!). The 8oz can of Slime for 12.00 total would be the best buy it seems, for that amount, but my prayerful purchase was a lot of the Monkey grip kits, at about 1.10 a piece including shipping (Blain's Farm & Fleet)
Thanks and God bless for all the help and info. Hope it will be a help to others in the future as well.
