Why does Dodge go cheap with their steel?

If you want to take your new truck and help it out, pop the door panels off, drain plugs off etc. Anywhere that the water can lay, and spend a few bucks for some cans of Dinitrol AV25. This is an aerosol spray type of C.I.C. or corrosion inhibiting compound. Its used in aircraft to prevent corrosion in moisture prone areas. You can also buy a thicker brush on version called Dinitrol AV100D. It can also be thinned to a spraying consistency. Water likes to lay in the pinched together areas inside at the bottom of the doors, rockers, hood, tailgate, fenders et . Spraying enough of this in there prevents it from doing that. After spraying, make sure the drain holes are clear. Shoot it inside the rocker panel drains, up inside the hood etc. especially the fwd edges where the metal is spot welded together. Anywhere there is a seam, thats angled to hold water, water will get in, lie there, and theres going to be problems down the line. I'm in the airline industry and we use this and another product called CorBan to prevent corrosion on the aircraft. The entrance areas, as well as below the galleys and lavatories are the worst areas for corrosion. For water displacement, these products work quite well.
