Well, I am back from being away.

I need some help in deciding what finish to apply to my aluminum tanks.
If any.

I have two H.P. Catalina 80cf alum. tanks, that currently, are coated with
what appears to be a clear coat which is chipped and now starting to peel.

This clear coat is red in hue, I understand this was popular and some of you
may remember these Catalina's.

I have passed these tanks to a trusted fabrication shop, the owner of which
is a friend and diver, who will have the coating removed. I am not sure if
they will use soda or walnut for the blast.

Once the coating is removed, I am thinking of having them polished and
perhaps coated with a clear powder coat or perhaps anodized.

I am not sure.

Any and all advise on coatings, anodizing, polishing or whatever, will be
gratefully appreciated.

I read where anodizing can be done with a multitude of different colours.
Perhaps cooper or bronze.

I have an old friend of mine who told me a story about diving on the B.C.
coast many, many years ago.

Apparently a large group of divers travelled to the coast for a week of
diving and found they were short of bottles for all to dive together.

Their solution was to empty and clean fire extinguishers for use as dive
bottles. I am told this worked well.

Lets see, cooper coloured anodize, laminated brass plate, circular carry
handle.
Yup, those Catalina's could look like old fire extinguishers.
