Underspray question
When my grandfather purchased the 1981 F150 off the showroom floor at Lonestar Ford..He paid an additional price for an under spray, under the truck to prevent rust from getting there here we are in 2013 and it is really rusty and it has been since atleast 07'?

Undercoat is good for TRAPPING moisture against the metal and rotting the truck out. It is good in theory, but it doesnt work like you would think

I've always wondered about sacrificial anodes like you would use on a boat.
It takes a lot of energy to 'win' iron from its ore.
That energy is always trying to get loose in the presence of oxygen.
In the end nothing is going to change the laws of thermodynamics.

We use the anodes when we burry underground wire at a pad mount transformer. I haven't been doing it long enough to see the long term results though.

Electronic rust preventers can work fine if they are forcing electrons backward.
Just a tiny charge will stop most galvanic corrosion
Have you ever used electrolysis (sodium carbonate and an anode) to reverse rust?

Previous to then, they had all suffered as badly as each other. The change was as if a light was switched on.

OMG! That thing completely disintegrated in our salty New England winters.
Really it was the crap recycled steel.
Carbon is the most cathodic element and free carbon in the steel caused horrible corrosion.
The Japanese didn't take long to figure it out.

I think you should take it back to the dealer and tell them you want Grandpa's money back. You won't get any money, but the looks on their faces will be worth something.

We got an undercoating by a company called Ziebart applied on my mom's 1977 LTD II in a suburb of Chicago, and the car didn't still didn't have any noticeable rust in the 17 years we had it.
