Was never scared of scuba until now

I bought an old pacer xl and went to clean and replace the parts that need to be cleaned and replaced. I ran across this LP seal.

What are your thought on how this happened? Do you think the person who breathed this is still kicken? I was thinking maybe its the exhaust from one of those floating compressor rigs.

For me it looks like Aluminum oxid from a bad tank which had water inside which dried.
The aluminum 'rust' is aluminum oxid.
I'd like to see the filter in the 1st stage.........

I agree. This is what happens using my very old Luxfer aluminium twin tank (Aralu).
these were made of an alloy which did suffer of galvanic currents, causing anomalous corrosion, oxidation and failures. No one wants to fill them nowadays, after some bad cases caused explosion...

Unfortunately I didn't save the filter on the 1st stage. I did not notice anything wrong though. This is not saying much being the stain is closer to the color of the filter and I am slightly color blind.
