Think this will last?

[chris85]

So I've been cleaning up rust on the underside of my jimmy and wanted to get some opinions of how well this will last. Mostly just surface rust, metal is all still solid. First, hit it with a wire wheel, cleaned with acetone, applied some Eastwood rust converter (ran out, now using Ospho) cleaned again with acetone, then applied Eastwood rust encapsulator and finally it will all get Al's liner.

I know media blasting is a better option but I'm limited by my space and resources.

I bet you'll get fairly good results with that. I bet it'll be a few years before anything starts to come back.

Jab it w/ a screwdriver. Make sure it doesn't poke through. I had some rust on my floorboards and when I cleaned it up it looked solid until I did the screwdriver test.

 

[chris85]

Yeah I've poked it pretty good. Found a couple spots that I cut out and patched up. Had to patch up a rocker too. Hoping the bedliner will really keep it protected. Eventually there will be bedliner inside the tub as well.

Update:

I was able to apply the Al's liner to the front half of the body today. I'm not very satified with the results. Had to roll it on and a 20 min pot life is not nearly enough time. Still, it may look sloppy but I think hold up well.

the thing that fails with an encapsulator is when it gets compromised somehow and allows oxygen and moisture into the area again. When that happens the rust is hidden by the overcoating film until the metal starts expanding from the rust and breaks through the film and the snowball is rolling.

So you're saying as long as the bedliner stays intact, I shouldn't have problems with the rust returning? But if it does return, I probably won't know it until it until it is breaking through somewhere?

Yup

sad but true. I've seen it in action first hand....and I don't want to think what throwing salt into the mix will do to accelerate it.
BUT....you've got to do something to keep the rust away, and your doing that...first and perhaps most important is stopping the spread of the rust...mechanical removal of the rusted areas is the best...get down to clean bare metal and start your refinishing from there....which you are doing by cutting the rust out and replacing with solid metal. I think the biggest thing now is to be diligent about watching for anymore formation of rust. Well done man!

Thanks! I just wanted to attack it with every means I could. I would've loved to have had it blasted then coated, but that just wasn't an option.

not every problem has the ideal solution available to deal with it.
