Cosmoline to preserve cast aluminum on? Rust Veto 342?

Has anyone ever tried the Rust-veto 342?

I want to preserve the natural cast finish on a show car, and when it sits in the winter or gets humidity the aluminum gets chalky.

Anyone ever use the more translucent cosmoline to coat cast iron/aluminum pieces?

Pics would be appreciated.

Thanks

Use ECS Automotive RPM product. Works excellent!
