2nd Gen Non-Engine/Transmission preventive maint. for rust on doors

[VolsFan]

Hi.

Finished detailing the truck the other day, and I am pleased to see no rust anywhere on it. I know I am definitely in the minority of 2nd gen ram owners that have rust free doors. There is a very tiny spot of surface starting on the inside drivers side inside lip up top near the paneling(I have the sweeps off the doors), most folks wouldnt notice it. Question is, what can I do to stop the rust from happening now that I know its an issue on these rigs. My 99 had rust on the doors, I grinded it all down and put por-15 on it and sprayed bottom with bedliner. When I sold it, there was a spot on the pass. side lip where it was breaking out. The buyer didnt really care, it was still a solid truck. I make sure I wipe the bottom of the doors fairly regular to keep debris off, I want to hold on to this truck for a long time and keep it in good shape.

I met a guy a number of years ago with a GM pick up that was about 15 years old. The paint was really faded but the body and undercarriage was totally rust free. He used to take his used motor oil and thin it with diesel the put it in a garden sprayer and spray the inside of the doors under the hood and the underbody and frame. He did this a couple of times each year. I think the environmental people might get a little upset these days.

I remember reading a post from another TDR member who did something similar, but the mix was fresh motor oil and WD40 in a 50-50 mix. I've never tried that myself, but I hose WD40 into the channel at the bottom of the doors probably twice a year.

check out fluid film. I buy it by the gallon cans and spray the underside of my truck every year and it does well. I got turned onto it by Ohio DOT they spray it on all their plow equipment every year. They also have aerosol cans available to do inside doors and such.

I'm also planning on taking the wifes car in to have it treated with Ziebart although I believe its best to do something like that on a new vehicle or one that has zero rust. Any kind of surface scale would just get trapped underneath. Someone on here recomended KROWN to me, you may check around your area for a local shop that applies it. They spray a rust prevention inside door panels, wheel wells, under carraige, etc. That seems like a better route for older vehicles that may have a little scale on the frame. Its also something you have to have done every year.

Krown is what I have used for years up here. It is also used by Hydro One on the trucks in our area annually. It will creep into the door seem folds (which ziebart will not).

If you spray Krown on a leaf spring sitting upright on the floor(spray well only around the perch area), you will find that after a day or two, it has crept uphill to the ends of the leaves.

Not affiliated in any way, just a long term user (20yrs or so), and every vehicle I own is done annually even if it rarely sees winter.

I do the wd-40 trick, but a guy also needs to get in there and vacuum all the crud out of the outside bottom where the inner and outer door skin meets, its a tight spot, allot of fine dirt/mud builds there and will stay wet for along time and start the rust process,,, I use a small pick and stiff paint brush... if it stays clean it will drain fine... . its the dirt/crud that gets the door.

Never thought of spraying into the channels, seems like a no brainer. I had some PB blaster in the toolbox and sprayed into them earlier this evening, before spraying compressed air into them which knocked out a little crud. Will check into some of the other more long term options also. Thanks!
