Luigi who? snipes,

Just follow the directions in the patch kit to the letter. Avoid
the FAQ because it's full of bad information on this subject.

That's a pretty broad brush you use without specifics. Wold you
clarify what it is in the the referenced FAQ that you find "bad
information". If not, then I take it you are just another disgruntled
sniper that arise here on occasion, usually under an alias. You
wouldn't want to be quoted to your face on this would you?

Also, don't assume that the patch failed. Did you forget to remove
the culprit from your tire before putting the tube back in? Or
perhaps there was more than one hole to begin with.

That should be evident on second inspection, after it went flat again.
Was the patch leaking or was there another hole? The reason for the
sandpaper in the patch kit is unknown to many of those who write the
instructions, something that is apparent from the advice to "rough up
the tube" before applying glue.
