Rust Prevention Methods?

Hello. Was wondering about rust prevention: 2 questions:
Premise: I live and work by the coast/on a boat, and my taco spends easily 60+ hours a week within a few hundred feet of the water, sometimes even parked ON the wharf for lengthy times.... I like to rinse the bottom at LEAST once a week- I've seen the horrible things salty breezes can do to metal.

But I wonder, am I threatening to further rust my taco by simply wetting my undersides weekly? **Is there a recommended method for drying things off?**

Also, on our boats we stick blocks of metals- with higher oxidation potentials- on various parts of the boat. These blocks essentially take the bullet of oxidation/rust and help maintain the metallic components of the boat. **Is there a similar method for road vehicles?**

I thank you very much for your time in reading this. Any feedback at all is highly appreciate!

 

Fluid film. Coat everything underneath. Everything. A lot. With fluid film.

 

Not sure how sacrificial anodes would work on a land based vehicle since they normall rely on salt water as the conducting medium to complete the "corrosion circuit" but I too have wondered about how I could utilize this principle.

To treat rust, I use this product called Ospho. Works great but in the end, rust is still an ongoing maintenance issue.

 

Can't stop it. Can only fight it tooth and nail.

Touch up surface rust before it has a chance to become a problem. If it's already a problem, get it cut out and patched at a good frame shop. Fluid coatings prior to winter never hurt, just clean well beforehand. Also, moving the fuck out of the Northeast (if there).

You're on the right track with frequent washes. You're washing paint, not metal, so no, you're not worsening things. Keep getting whatever the breeze is depositing there off the vehicle.
