Air Conditioner Question

I was cleaning out my roof air conditioner and noticed the Freon cylinder was rusting. My question is.... is it ok to put WD-40 on it on possibly spray paint over the rust?

Well - if you put WD-40 on it - paint won't stick to it. And the AC unit will give up long before the rust attacks it. I have a 98 winn and replaced both roof AC units in the last year. After 15+ years, the compressors gave up.

Use Acme Rust Control paint or Sherman Williams Rust control
Flat black would be my color choice.

Yo may need to brnish it a bit to remove loose rust.

Not sure but Navel Jelly might also work there.. This is a chemical that reacts with the rust and in this enviorment I will not recommend it, But it MIGHT work.. Might also do bad things.. Acme/Sherman Williams Rust control will work, No fish oil, just zinc.
Home is where I park it!
