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 .......
