There are shops ( I can name at least one here) that had major moisture
problems in its compressed air systems. The quality of the  moisture
level is only as good as the maintenance of the air system. If an air
filler is pumping water into the tank along with the air all bets are
off with respect to internal rust on steel tanks and some corrosion
(Al02) on Al tanks.

I also think something along these lines was the case or one of the
guys best friends asking for a favor, but with other FL explosion in the
not too distant past, one would think the shop would have the brains NOT
to fill out of Vip/hydro tanks at all, and even with some caution
without the V+ as Michael has suggested his shop follows.
