keeping our trucks from rusting more

[rustyg]

I was wondering what you do to keep trucks from getting rusted out, I plan in driving mine on the roads, in the snow alot. I have some friends in the car wash biz, and I was thinking about fabbing a under carriage spray rinse, possibly with a rust inhibitor, something I'd drive over when I got home. Is this idea worth looking into, or are there more effective methods.
