I believe it was cosmoline dipped? Not sure on that but anyway I would like to get my lower control arms to look somewhat factory with something out of a rattle can. Its on a 71 Barracuda. I have the lowers off right now and want to clean them up. Thanks.

People have mentioned the Krylon battery terminal protector and then using a satin clear over the top of it. I just ended up using the spray can from eastwood, rust proof inhibitor.

No matter what coating you decide on using, this is the result you are after. This is an NOS example. They were (partially) dipped in Cosmoline and partially bare metal (they were not completely dipped). If you want the ultimate in originallity/correctness you can still buy Cosmoline Buy It Here Linky . After the part is cleaned of all rust treat it with a metal prep like Ospho, rinse it with Acetone or thinner (not water) warm it with a heat gun and apply RPM to the entire arm, this will protect it from future rust (even under the Cosmoline should it wear off) and then re-dip it in Cosmoline up to the hole shown in my pic.

Good pic Scott.. I knew they stopped that dip line somewhere but I chose to take it all the way up to not see any rust potential at all in the future...

so I'm assuming you dip the arm in two separate pieces insert the new bushing then reassemble?

The vendor for Chrysler making the lower control arms was IIRC, a division of AO Smith, a railcar axle manufacturer at the time, the LCA's; after the two halves were rivited together had the ball joint end placed on a hook conveyor that ran the parts thru a molten cosmoline bath, the ball joint end was not covered as Chrysler wanted no spinning ball joints, or assy problems on the line...I'm sure the bath height varied some, due to the number of arms running thru the bath, as well as the level being maintained by the workers...so the dip line, I'm sure varied on the finished project, although I'm sure engineering supplied some specs to be maintained, it's also been documented that excess stock/dealer inventory was to be coated in Black enamel, and the arms were to be completely submerged to prevent storage wear/rust.
The interview with the manufacturer and employees is avaiable on the Winged Warriors Club site

Here another NOS LCA that's been sitting on a shelf for 30+ years with the dip line in a slightly different place.

Found out someone installed an a body lower control arm on the passenger side, isnt that nice. They also did some creative welding on the pivot. Glad I wanted to change the bushing to find this mess.
Ill be using the krylon spray cans. It is not to be 100% correct. Not copper paint either?

In production they were most commonly the cosmoline coating, but black is possible. One of my customers who worked & retired from AO Smith, told me that they also manufactured parts for railroad cars. When the cosmoline dip line was being used for that, the control arms would be done in the black paint dip. He had detailed stories explaining how the different pieces were formed and assembled... should've recorded him.

Yeap, just make sure the job isn't too neat, you need to have runs... And, the arm needs to be hanging...... Would be funny looking with run marks going in the wrong direction....
