I guess it you were changing tyres regularly because of high mileage
then I guess it could be 'expensive' but then for what it normally
costs to treat 4 tyres, divided into those miles and the convenience
of not having to 'suffer' a puncture, it might be worth it for even
stopping one puncture per set?

YMMV etc.

I have found it gums up the valves so I never use it .......


You haven't because the chances are you have never used the likes of
Punctureseal.

Also, I have use it for over 20 years and *never* found it to gum up a
valve. Apart from the fact that it doesn't, it can't, as it's nowhere
near the valves?

So, the chances are you are referring to either the emergency
get_you_home / temporary latex foam in a can type solution or some
inferior product (that I have found myself).

I quite understand how if you are only familiar with the poor /
temporary products that you wouldn't be impressed with them, that's
why there are generally cr*p and 'the real thing' with all things in
life.

A cheap / cr*p electric drill wouldn't be a good advert for all
electric drills etc.
