Redneck rustproofing
My brother used to joke saying just spray the inside of the door with a can of WD40 to keep them from rusting out.
...which leads to my question in all seriousness; Is there a product made for this or has anyone used anything successfully to rustproof the doors from the inside?

The "WD" is WD-40 stands for "water displacing" so yeah, it can stave off rust. However, the problem is WD-40 is lightweight so it'll wash away real easy. Ya need something goopier like motor or gear oil. There's some stuff on the market that feels like tree sap. I don't recall the name but it sticks like snot and after a light coat of dust no longer attracts anymore to stick to it.
I just bought a 70 bump and it has had an historical oil leak so the cab's underside and mid-section of the frame is coated with a mix of oil and general dirt/dust. I'm not gonna wash it off until I am about ready to tear it apart cuz if I do, the metal will no longer have a protective coating and start rusting.
You could try roofing tar but that's be totally redneck... just remember to keep your drain holes open.

If rust is already there, then you are going to need to address that first. You may be able to get away with POR-15 once you clean off any scaling rust flakes but POR-15 likes to have a light coat of rust to adhere to so cleaning it may-or-may not work.
Once you have the rust problem solved then you could use spray on rubber undercoating or something along those lines.
Just my 2 cents.

I know an old farmer that bought a 78 brand new off the lot and as soon as he got it home he took a weed sprayer full of used motor oil and sprayed every inch of the underside of his truck also sprayed all of the little nooks and crannies that he could get into in the bed the cab and the engine bay, as soon as he finished he took it for a drive down a silt filled dirt road about six times.
Long story short when he passed away last year his truck was still rust free....i realize that i live in a dry area but my truck has lived its entire life in the same area and it has the rusted out fenders and it has seen the same kind of work and use.

If you can get your hands on this stuff it is very much worth using:
AMLGuard MIL-DTL-85054
As a veteran, I can attest to its use on submarine-hunting aircraft.

You mean to tell me we have aircraft that fly under water.... 
Sorry I had to.
I know the P-3 Orion you flew was way above them, thanks for your service.
Yea you Navy guys had alot more corrosion issues to deal with, than us ol land based knuckleheads.
Ziebart will rust proof them for a fee, but I like the more than WD-40, less than roof tar trick. POR-15 rocks from what I hear on here.
Sorry for the HJ.

WD-40 does have a couple of uses. Drying out a wet distributor is one. Useless for freeing rusted bolts. It does work well if you know you're going mudding. Spray it down and most of the mud will drop right off.

Don't know if you get it there, but a GREAT product that we use offshore is made by a company called Galmet that do all the cold galv sprays etc, but this one is called "IRONIZE" - it says to leave a small amount of rust so it can turn it into Magnetite, but we have done experiments and the cleaner you can get the surface, the better it works. Probably because it actually bonds to everything and forms a laminate barrier that works as a universal key for primers to then stick to.

if you want something that will never ever ever rust, in a million years, lol. roofing tar. not just roofing tar, but i mean hot tar. my 74 f350 dump truck got splattered with hot tar when one of our guys dropped a bucket of hot tar off of a roof. and that was 10 years ago. and its still on there, and isnt coming off anytime soon. id probably have to have a die grinder to take it off. though it looks ugly, and is about a 1/4 inch thick spots all over it. its never going to rust.

Reason I ask, back in 1978 I bought a 67 Chevelle SS from the original owner who was in the Navy in '67 when he bought it in Lynchburg and drove it back to San Diego where he dismantled much of it and coated it inside wit a black gooey stuff in the "Hobby Shop" as he called it on base. He said the stuff waqs something the Navy used on stuff on ships. Inside the trunk, up the roof pillars, the inside of the roof, the fenders and frame, everywhere that wasn't visable and some that were if you looked close underneath .... and that car never showed any rust. He even then did the trunk in black indoor / outdoor carpet. Of course, he put all the interior / headliner / etc back.

Nope. AMLGuard feels like a mildly sticky cooking oil. It can be removed with a solvent or with a rag dampened by more AMLGuard. I didn't join the Navy to go on a boat - Hence, I purposely chose the aviation field where there was less chance to get stuck on a ship.

Grease, tar, POR-15, they will all keep panels from rusting. Someone, sometime sprayed my inner door skins with rubberized undercoating and they are clean as a whistle. Someone mentioned Ziebart. I don't know if they have gotten any better but my father had a 1980 AMC Spirit that was treated with Ziebart and in the Connecticut winters it rusted out in about 6 years. And when I say rusted out I mean BAD. The thing literally fell apart from rust.

I mentioned Ziebart, I have no business affiliated with them, just threw it out there for the guys that do not have the time or tools to do something like that, that's all.
My tow Dodge's inner doors were done by them and the truck came outta Michigan and they are pretty good, but time is telling on them.
