abranz........I work at a heavy truck shop and you wouldnt beleive what the salt and calcium chloride do to all the wiring on these OTR trucks and trailers. I don't know how the trucking companies can afford to keep all of the lights working to be quite honest. It will literally eat an exposed 12gua. copper wire in a matter of a week. I have also seen it eat completely thru a differential housing to the point it was leaking oil. Granted that particular case was on a fuel tanker that probably has never had the underside of it washed but, cmon...........those housings are at least 1/4" thick, probably closer to 3/8' thick. This stuff should be outlawed.............or then is it the governments way of getting older vehicles off of the road??? I'm not a conspiracy theorist, but It makes you wonder........sand and gravel worked for a long time, and there is more of it available locally than there is salt....................how can it be cheaper??????
The day after I bought my '76 F350 supercab in March of 1976 I drove it to the local Ziebart facility and had it "ziebarted". Although the truck has spent most of it's life garaged, and only has 74K miles, there is no rust on the truck. I smile every time I see the little yellow plugs that were installed in the access ports that were drilled into the "cavities". I remember the "petroleum smell" that lasted for quite a while, as well as the minor "dripping" that lasted for about a week. I don't know if they're still in business or not.
there has been some people on here use bed liner spray for the under side to keep it from rusting.

I'll second that bed lining DOES NOT work as a rust inhibitor. I had the entire lower 6 inches of my 01 sprayed with bed liner to help slow a rust problem. I was told that it was a temporary fix and was ok with that. But instead it accelerated the rust and made it much worse.
