"Rust is composed of iron oxides. In colloquial usage, the term is applied to red oxides, formed by the re and action of iron and oxygen in the presence of water or air moisture. Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen – rebar used in underwater concrete pillars is an example – which generates green rust. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances.[1] Rust consists of hydrated iron(III) oxidesFe2O3·nH2O and iron(III) oxide-hydroxide FeO(OH)·Fe(OH)3.
Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable, and provides no protection to the underlying iron, unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo equivalent corrosion, but the resulting oxides are not commonly called rust."Wikipedia
A customer dropped this truck off here at Dunlop Customs in hopes that we would be up to and able to tackle the restoration challenge. The frame had a lot of rust and deterioration happening all throughout the back half of the truck.The frame and rear end parts had seen better days.
Someone had previously tried to stop the rust and holes from forming before we had gotten to it. Their fix was to weld some random pieces of plate over these spots. That sucked because to even get the cancerous rust I had to pry, cut and hammer off all these temporary fixes. Oh did I mention that the previous owner just sprayed POR 15 all over the under carriage? Yes that is right he just sprayed it right over the rust and everything. Which I understand that this is what it is was designed for, but you really should take the rust off the frame before spraying it so that the rust doesn't continue to eat away the frame underneath the paint. It didn't come off easy, even with a wire wheel and a 4.5" electric grinder.
I had to literally scoop the rust out of the inside of the frame in order to make sure that the rust would not be a further issue in these locations. Here is a picture of what I found after I started to torch cut these holes for the new steel. I filled 3/4" of a bucket with rust and old frame pieces.
The new plates have been welded into the place, sanded smooth, and wire wheeled for the factory look. Not like that shady backyard/ garage shop fix that was going on before.
Next up on the list of things to do was to address the mechanical side of the Jeep. The axle was pulled so that the rusted out coil spring perches could be replaced. After cutting out all the rust, new plates where built and welded into place in order to insure that the coils had a sturdy platform to ride on.
Axle was painted and the new parts arrived!
Frame was repainted!
The last thing was to make sure that all the new suspension links and brakes work through the travel. Everything looks good and all the hardware was second checked to insure safety and reliability.
