Stopping, but not fixing rust on a beater

[RockDoc]

I've got body rust pretty bad on my 62, and really need to put a stop to it if the truck is going to remain servicable for a few more years. I don't have interest in fixing/restoring the body though, as I have another clean truck in the works and will use the 62 as a winter/trail beater so that one doesn't see salt. I'm not too concerned about absolutely killing the rust, just want to slow it significantly.

So here's what I'm thinking, please give me your thoughts.

1 - Sand/grind/wire wheel away as much loose material as can be done easily
2 - Go at everything exposed with phosphoric acid to chemically knock the rust down some.
3 - Deal with hole/gaps as seems prudent (fiberglass, pop riveted sheet, expanding foam, pine cones and white glue, what-have-you)
4 - Coat exposed material with an asphalt based rattle-can undercoating (which hopefully with form a flexible and oxygen-consuming immediate coating over the metal).
5 - Go over the asphalt stuff with a paintable rattle-can undercoating, masked to follow body lines.
6 - If that looks too crappy, give the whole truck with cheap DIY paint job.
7 - Get at the inside of the panels with a suitable rust inhibitor.

Alternate easy and cheap suggestions?

With the understanding that you are just delaying rust:

Wire wheel and phos acid wash are great ideas. I'd add ZeroRust (about $50/gal US) and skip the asphalt undercoating. Know that the ZeroRust is also avail in aerosol cans.

I'll have to take a look and see if we have it up here too.....

brother its simple

PPG -DTR and some MEK

And of course the rest is up to you ....wire wheel sandblast whichever.

I can tell you the DTR wil hold steel ....just fine

Thank you sir. I assume your suggesting MEK as a thinner for the DTR?

How is the frame?

That's where I would spend most of my time. The body can rot a few more years without harm.

It's solid. I should give it another go with fluid film though....

Will fiberglassing resin stick to Zero Rust okay, of should I sand down through the zero rust where I'm going to be glassing? Ditto on body filler, will it stick to ZR, or should it only go on bare metal?

Get to the nearest Krown QUICK, and go again in 6 months!

Don't ask questions just go it's rusting as we speak

 

[fliphkd778]

DUDE!!! I've got to get me some of that DTR!
The specs show high resistance to acids, abrasion, bases, and solvents!

automatic transmission fluid in a pump garden sprayer and spray the underside and the rusty spots down. done. CorrosionX works great too and doesn't drip as much.

stay away from the rubberized stuff. unless your metal under it is perfect then it will create more rust and rot underneath without your knowledge.

Fluid Film, thinner, a garden sprayer and a brush to spread. That's how I do the frame.

Cut and weld. You wiill learn alot,stop the rust,and the welds wont disapoint you while you are learning, 2 cents Mike

Progress so far..... wire-wheeled, acid etched and wet sanded ready for zero rust tomorrow. Other than the bottom of the PS quarter panel, there isn't much empty space to bridge....
