Re: [PSUBS-MAILIST] protecting aluminum parts

Hmmm. Maybe one of our metal guys will take a shot at that. The only thing I 
ever did similar was replace a piece of 304 stainless in the oxygen system on 
one of the boats when it turned to rust on a single dive. It should have been 
316 to start with, but we were all surprised that it rusted like that. I 
wonder if we could have polished it out and by doing so, sealed the pores and maybe 
made it shinier and less likely to do it again? Very strange. Vance
