Undercoat to prevent rust?

[buddy]

Where did all the rust proofing shops go in Jacksonville? I opened the phone book and there's one little line in the yellow pages, some small local body shop. No Ziebart or any other national chain, No Guarantee...You would think with all the salt water/air mix around these parts, a rust control shop would be a profitable business. Maybe they all got rusted out and closed. Who knows...
