Hello sir, What's the best way to protect the exterior of a bare aluminum cylinder?

[@scubatechkeylargo]

Fresh water rinse after every dive. Skipping a rinse will allow salt to stick to the walls of the tanks and begin the corrosion process. Once you see salt sticking to the walls, wipe it down with a wet cloth. A light grit wet sanding sponge works awesome on older tanks. No need to apply any protective coating to the exterior. The maintenance after the dive is what matters. Thanks for the question.

@@scubatechkeylargo Would that also apply to steel cylinders,no coatings just keep them clean?

[@scubatechkeylargo]

Correct, galvanized steel already has protective coating, painted steel has several coating of protection. Fresh water rinse and wipe down will extend the life of your tanks.

Good information. Thanks. Earlier today someone shared a picture of an air cylinder that they applied a vinyl wrap around. Looked cool, but I can only imagine what it might do for corrosion.
