Ok, two things from someone who owns a machine shop (and hangs out with people who talk about metalurgy and metal protection all the time).

First, WD-40 is for cleaning things. It is a solvent. It says lubricant but water is also a lubricant...so are lots of things that do a poor job of lubricating.

It might be OK for thinning up what the smart person used to actually protect their metal items later when it's time to use them.

Be cautious using protectants that "laquer" for protection in the cylinders for obvious reasons.

My personal experience is that Marvel doesn't. It is thin enough to spray and reasonable protects *unexposed* surfaces (no rain, acid...etc).

There are other products, but they are generally purpose built for industry and not available at the local auto store.


Secondly, I've watched long threads on the ability of springs to lose their "springy-ness" and the conclusion is always the same... springs can only lose their "spring" under motion...not stationary...even compressed. Only motion (use) can change their molecular structure.

Hope this helps
