Rust Proofing the MJ

[Megadan]

I did a little bit of searching and found some tidbits here or there, but I was wanting to try and focus ideas, methods, and generally any and all ideas and approaches to rust proofing an MJ.

This topic comes to light because I will soon be replacing my drivers floor pan.  I just got my C2C pan in the mail, so it is now a matter of waiting for a good time to do the work.  While I have the floor pan out, I plan to clean out and treat the frame section from the inside.  Unfortunately, this is not as much of an option on the passenger side since the floor pan is still good and I don't feel like replacing it "just because" or cutting the thing out to gain access to it.

Thus, I am looking for any methods to cleaning out and treating the insides that have worked for others.  I am also looking for any approaches to treating the cab corners, rockers, etc.  I wouldn't mind drilling a hole or two and plugging it if necessary if it means I can keep this truck from turning into a rusty wreck.  I do plan on pulling the bed later this year and chassis coating the frame and cleaning up, treating, and sealing the bed from the inside/underneath.  My main concern is the unibody side of things.

I am more than aware of the various different kits out there.  What I am looking for is any specific methods people may have used that worked well for them, including methods for cleaning out the insides of frame sections.

flushing with a powerwasher has got a lot of junk out for me

Using holes in the frame rails?

That's what I do during my weekly truck wash, you would be amazed at how much crap will come out of those frame holes weekly

yep all currently drilled holes. I prefer to go front to back a couple of times. and flush back and fourth a little

for body rust, there really is no way to fix it without welding in repair panels. for rust on the chassis, clean as much up with a wire wheel and coat it with POR15. For hard to reach areas get 3m rust fighter II they even make a wand that will coat the inside of the chassis

Rust is cancer once you have it its there forever. Whether you see it or not.

Aside from my floor pan, which I already have a new pan to weld in, the truck is mostly rust free.  At least to the point that I can wire wheel away, treat, and paint over any that is there.

 

What I want to do is try to treat the areas I can't easily see to slow or stop any rust in those areas, or at least inhibit it for longer than normal.  My main point of this was to try and see if anybody has any tips, tricks, or methods they have found and used to do something similar.
