Can the underbody be cleaned up?

[444]

My superduty is about 5 years old, and its going the same way as the rest of my family's superduties. It seems like the underbody paint is total garbage. The rear pumpkin is completely rusting and the black paint is flaking off in sheets. Any diy cure for this kind of thing?

I was thinking just sandblasting off whatever i could, and re-painting. Is blasting sand bad for any seals etc?

Maybe just a 3000psi pressure washer and 0 degree tip?

And lastly once i do get all the old paint/rust gone, what would be a solid "coating" to go with. Paint isn't living up to my standards if i'm going to keep this truck 10 more years.

I hate that too, if it was not something that could be easily seen i'd let it slide. But most of us are able to see the underbody of our trucks. I would be more afraid of pressure washing with a 0 tip (I know personally that it goes to bare metal if you get close enough ) but sandblasting might be better. It seems that with a sandblasting gun you can get a little more control, and stay dry.

honestly what you are experiencing is normal, and you risk more harm than good by trying to fix something only a guy on a creeper can really see......just my two cents...

I hit my whole frame with a cup brush on an angle grinder and painted it with a couple of coats or rustoleum. I can't stand looking at a rusty frame.

If you clean the big rust real well, they have that paint that turns rust to primer somehow. Then once you do that you could spray it with a real good black that would last a while. That rust to primer stuff works pretty good if you clean it pretty good first and then it is supposed to stop the rust that is there from growing. Just a thought.
