Vacuum Canister

[mikeydf14]

Just received my new vacuum canister for my head light doors. I haven't seen one in many years and I forgot that they look like a painted tomato juice can mounted sideways on a flat piece of metal!  The can mounts below the battery tray, another wonderful Dodge engineering idea, and is subject to battery fumes and rust problems. I was thinking of using a top coat on the can to help ward off the affects of the battery.  I thought about using some Rust Oleum Spray on bed liner which is very durable. Any thoughts?

Just use a sealed or an agm battery. Alos teh batttery tray will rust out long before the canister. And who if they seen the battery leaking wouls let it continue to leak all ove the place?

If that's the case of course the tray will be the first to go. It's more of the battery vapors that I am concerned about not a leaking battery.

The fumes should go up unless they are heavier than atmosheric air, in that case, they would go under the car.  The only threat that I see to the vacumn canister is the rust issue.
