Zinc Dipping for Rust Protection

I haven't noticed anyone talking about zinc dipping. Instead of pondering the merits of primer paints' porosity and so on, why not take your frame to a galvanizing shop and have it dipped? Zinc is one of the least noble metals and as a result the galvanic process actually works in your favour for once. In the event of a bit of frame metal becoming exposed underneath the galvanizing form a rock chip or whatever the ensuing electrolytic process will actually have zinc adjacent the exposed metal migrating to it to close it up and further protect it. You can paint atop the galvanizing should you want a more authentic appearance and have the comfort of knowing that the little inferior zinc molecules underneath are quietly taking care of your frame for you. If you are just attempting to preserve your frame until you make further decisions, you can dip it and put it aside without any further attention until you decide to proceed.

The same applies for body panels and other metal components throughout your vehicle. It is not expensive, quick but for the size you would have to locate a galvanizer in your area with a tank big enough. Certain auto manufacturers do this for the complete body shell prior to painting - Porsche comes to mind.
