That's not what the patching training I've been to taught me. (for
automotive and industrial tires, notbike) As I
recall, abraiding a tire to #2 texture doubles the surface area
avaliable for the glue to cross link with.

So is a cotton ball. Fluff it out, and drag it aroundthe inside of
the tire . It'll snag on the tiniest piece of wire sticking through.

Certaainly my prefered method. I have a giant bottle of vulcanizing

Interesting. How do you keep that from drying up? That is always my
problem. Just a few months after helping another rider fix a flat my
vulcanizing tube contents gum up, especially during summer.

What I do is buy those small tubes of "glue", I don't remember the
cost but they are cheap and if I open one I just throw it away and
replace it with a sealed tube when I get home.

That prevents finding a tube that you've used before to be empty. It does nothing for the situation in which you find a tube that you haven't yet used to be empty.
