Yesterday, I brought my PS 104's into my local dive shop to VIP them.  =
Upon looking inside I was shocked.  There was alot of rust.  It wasn't =
fine little specs evenly distributed.  There were quarter size spots =
that appeared to be in a pattern.  Four of these quarter size spots were =
in a straight line traveling down the inside wall. There were a few =
other places with these spots but they weren't as patternized.  The =
spots weren't deep and pitted like I expected.  Most of it came off with =
a few minutes of wire whipping.  There were also quite a few spots in =
the far bottom of the tanks.  Both tanks looked about the same.  Anyone =
have any idea what happened from what I have described?  The tanks are 3 =
years old and last year when I looked inside of them....they were pretty =
clean. =20

I spoke briefly through the shop owner to Bill High the Tank Guy in =
Seattle.  From what I understand, he is the guy who writes the brochures =
for the cylinder manufactures with respect to routine care, maintance, =
and warranties.  He said it's probably from getting the tanks filled at =
shops with immersion tubs, and that they probably aren't being careful =
when filling.  The only place I have had my tanks filled at are the =
North Central Florida shops and the local shop in my area.  The local =
shop in my area has a brand new system with a self purging compressor.  =
I am not sure what name brand it is.

Since I have access to a tank tumbler, I'm going to use it.  What is =
commonly put in the tanks for tumbling?  The tumbler is at my uncles =
house and he uses some kind of metal pellets.  Have thoughts changed =
about what to use during the past 20 years?  My Uncle is from the Lloyd =
Bridges days of diving.  (:  How do I get the spots out from the bottom =
of the tanks?  Should I elevate one end of the tumbler so the abraisant =
is collected in the bottom of the tanks while they turn? =20

I appreciate your responses and If you have questions...shoot.

Brian
