I've got a bunch of patch kits that contain yellow "Propatch"

extra plastic wrap and all, didn't help. So we had to use my spare
tube.

Do you guys know a brand that is better and where a bunch of these
little tubes could be bought sans patches? Not so much for me but
for other riders because many reported similar problems.

The cement and patch are designed to work with one another. There are
chemicals on the patch that are activated by chemicals in the cement.
Different manufacturers use different activators. You will get best
results, if you don't mix manufacturers.

I've found the Rema Tip-Top patches with their tubes of cold
vulcanizing fluid to work extremely well.


After recommendations in this NG I bought a larger pot with tube cement
and with a dabbing tool mounted inside the lid. I have used that on
various patches and it worked well. It's just way to large to carry
along in a pannier.

Be scrupulous about sealing. The 8oz cans with a brush are a great value, but they dry out pretty quickly and inevitably before a home mechanic can use them up. Nonetheless, considering the price difference between the tubes and cans, you still come out ahead even with wastage. It's like buying the big bottle of hydraulic oil -- for twice the price, you get ten times more.. You can spill half of it on the floor and still come out way ahead.
