Rusty frame f350 ford dump truck

larry zielkowski · Jun 16, 2021

I purchased a 1989 ford f350 dump truck that needed some work. I have replaced the cracked exhaust manifold that had the broken studs and am on to the next adventure. Today I raised the dump body and began the long tedious task of removing the flakes of rust that are all around the frame, spring mounts, cross beams etc. I intend to now wire brush the frame as clean as I possibly can.
The advise that I am seeking is what to do next, after the rust is all removed, and I am sure that I have a solid frame? What would be the best method to protect it ? I have heard that covering the frame with a coat of chain saw oil would be a good way to do this. I live in Pennsylvania we got lots of snow ,ice and salt any suggestions would be much appreciated, Thanks Larry

This may be of use. It comes in several sizes of cans.

Once metal is rusted it's difficult to kill. I would recommend taking it down to bare metal and then treat it with phosphoric acid. From there I would prime it with an epoxy primer. That would do more to eliminate the rust than anything. Now, using epoxy primer it
has a recoat window. Check with the instructions, usually they have like eight hours before you have to topcoat it with something. It could be a sandable primer or the topcoat. Epoxy primer doesn't sand very good anyway so a filler primer would make things easier.

We have always used POR-15 for that sort of thing. It has gotten quite a bit more expensive recently, but I don't know another product. That Eastwood Rust Encapsulator looks like it might be good as well. I've never used it, but may order some to try out.

I have a lot of rusty things but mostly superficial stuff tractor loaders , engine covers and such and am always looking for a way to at least keep it under control problem is even though I am retired when I start to work on the rust something happens that is a higher priority and its hard to see it through to the finish. I am sure that many people on this forum have the same problem . time management and budgets are harder to deal with than any thing else

The products that are designed to encapsulate the rust are the only was to go. I have used almost all the different names, Por-15, rust bullet, eastwood, KBK, etc and like the Por-15 the best. I have used gallons of this stuff on truck frames, trailers, snow plows, you name it. They all have a couple problems. 1) that are UV sensitive to sun light and must be top coated. 2) if they get on you, that don't come off, so wear gloves. 3) nothing likes to stick to them, even their own products. I found the secret to that. While the Por-15 is still drying and lightly tacky, fog on a light coat of a spray can etching primer. Just a fog coat will bite into the still soft Por-15 and leave a tooth surface for the top coat to adhere to without sealing the Por-15 from drying. I have never had another problem with top coat peeling off.
