"Patch creep?" "Post-It notes?"

I don't know about all that. All I know is that my repairs don't leak.
If REMA patches were prone to leaking when being ridden immediately
after the repair, I would know it. So this whole discussion seems
pretty ridiculous. And the faq entry seems pretty ridiculous.

I suspect that many 'patch failures' are really caused by the failure
to find and remove whatever sneaky little object caused the original
puncture. The freshly patched tube gets stuffed back in the tire; 20
mins. later the tube is flat again; that DAMN PATCH FAILED! See it all
the time.

jb half right! News at 11:00!

In further "news," jb obviously has never had access to engineering
facilities, or he would have enclosed a substantial check or purchase
order to pay for Frank's work and equipment fees.

Here we have a picture of Krygowski's personal, unslain Jabberwock:

I picked out a full page color ad from a major magazine is what I
picked out. Targeted at the masses, the ad did not say "and that's a
lot for a VW" or "and that's a lot for an air-cooled engine". It
simply touted the number 100,000 to the masses because the advertising
personnel who wrote the ad thought that that number was impressive and
would impress the general car-buying public.

As for your buddies chevy, so what? Anyone can keep fixing any car
repeatedly. The point is that by far most people ditched their cars
from that era long before that point because they had gotten so
unpleasant.

Whoa, you have a can of REMA glue? Think of the
sniffing possibilities.

Is this the same stuff that comes in the tubes?

(I think) his expectation is that there would
be a decent chance that the patch would leak.

Patience is a necessary virtue when patching a tube.
Who has patience?

simply pointing out that someone is an idiot is not ad hominem.

Hey, everybody, Carl ages his tubes in the basement.

Who knows, I may have to ride my bike to Colorado the next time I go,
because my name may be added to a watch list for buying a can of the
stuff...
