How can I prevent my cylinder from corroding? (Damage to paintwork)

[Scubadou]

Hi guys, my cylinder has managed to come loose whilst I was driving and ended up rolling about in the back of my car. As a result of this it has collided with other equipment and has ended up with a small amount of damage to the paintwork. Can anyone advise the best way to tidy this up cosmetically and more importantly prevent corrosion?

Thanks in advance!

Wash the tank off after diving in salt water. Dry the tank after washing. Do not paint the tank.

If it's aluminium, then do nothing. If steel, spray chipped areas with ZRC® Cold Galvanizing Compound.

That happens so frequently to my tanks, I don't bother anymore. I just make sure to secure the tanks better and use a thick old blanket to pad the tanks.

The scratches show "character" and "experience"

Welcome to the forum. Remember not all Northern European summers are this warm and dry — it’s very much been the demo version of a diving summer!


Store it in a dry place. Rust doesn’t work then.

A blob of any paint could touch it up. Scratches on tanks mean it’s been diving.

Treat 'em mean, keep 'em keen

Thanks, I'll definitely make sure to pack them better!

Thanks for commenting and for the welcome to the forum! A friend of mine swears by nail polish but I wasn't sure!

My tins -- of which there's many as they breed -- are all treated as any piece of working equipment. They're covered in scars and don't rust and also don't fail a test as per below, picture taken 4 years ago and the flat bottom ones are still in the garage (now being used as banking gas with another couple of twinsets). The round-bottom ones were converted to sidemount and were moved on to their forever home -- and still haven't been painted.

I did once buy a pair of ancient 7's which looked awful but passed their hydro. So I painted them with some white Hammerite paint. Looked all white afterwards.
