Subject: sandblasting tanks
Date: Sun, 05 Dec 1999 00:29:52 PST
Well, I've just sandblasted my 19cf aluminum stange tank.  Couldn't stand 
all that yellow paint flaking off.  First sanded off the paint, as I'd seen 
someone else do.  Then got carried away and polished the tank with a buffer, 
to a chrome-like finish.  This lasted all of one dive, predictably, but what 
the hell.

Finally sandblasted it with 30 mesh sand at 100psi from a home compressor, 
and got a nice finish not unlike the "bead blasted" finish now available on 
Luxfer aluminum 80's.

So, what's the consensus here? Shall I condemn my tank, get it re-hydroed, 
or just continue on as usual?  Don't think I took off much aluminum, 
relative to the tank thinkness, nor did I get the tank hot. I'm inclined to 
go on using the tank, but open to other opinions.  Thanks.

Cam
