I wonder why some company doesn't begin to sell compressed

paint can before resealing might lengthen the storage life of the
paint.

Am I wrong in my assumptions that it would do this?

Luxury cars now offer a great seating option for politicians.
These seats blow heated air onto their backside in the winter and
cooled air in the summer. If sold to voters, though, the car
seats
are modified to just blow smoke up the voter's rump year-round

Air is about 78% nitrogen, the issue is removing the oxygen so you
need to pull a vacume first. They charge alot extra to inflate tires
wirh nitrogen, but how do they remove the oxygen, I dont think they do
at all.

I guess it depends where you buy tires. The local evil mom& pop place
doesn't charge a lot more or even more for that matter. They have a unit
similar to this in the garage:

By design a tire cant be fully deflated of air, air is 78% nitrogen,
so what is the true percentage of nitrogen in tires filed with
nitrogen, it will still contain alot of oxygen. But I guess if it
works its worth it.- Hide quoted text -

And I'd say it's just another scam to get more money out of unwitting
consumers. Nitrogen would seem to have no compelling advantage.
Supposedly it means tires are less susceptable to pressure change with
ambient temp change, nitrogen will leak out slower, etc. If you have
enough sense to check your tire pressure regularly, none of that
matters. And if you don't, then I'd say nitrogen is a poor
substitute.

Works for me. One of our vehicles has always had issues with slow tire
leaks. The wheels are clean with no rust and aren't bent. I had four new
tires tires installed at the local evil mom & pop tire place last year
and they used nitrogen this time (at no additional charge) and now the
slow leaks are gone.

New tires and more careful mounting eliminated the leaks, not nitrogen.

Nitrogen isn't really a scam per-se, more of a distortion. Folks found
that racing teams were using nitrogen for it's advantages when used in
low volume race tires running *hot* at a couple hundred miles per hour
and figured if the racers used it they should too. The reality is it is
of no benefit for normal vehicles with normal tires operated at normal
highway speeds.
