There's a few sources for real Cosmoline, and a few sources for imitations in paint form,....should you require "real" Cosmoline, be aware it will take a few weeks to dry, and it will remain somewhat waxy for it's life on the car,.....a 5 gallon bucket will run around $250, sprays run around $25-$50 for sprayable Cosmoline, ...simulated sprays from $2 to $25


it boils down to how "original" you want your car?, or whats in your budget?, or how durable, or resistant you want your finish?

I offer Real Cosmoline in a sprayable 14 OZ can, enough to do 4-6 sets of lower control arms, depending how "dark" you want the coating,....originaly the arms were hung by the ball joint hole on a conveyor rack, and lowered into a molten Cosmoline vat, leaving a small exposed area of steel around the ball joint hole, the reason was to avoid wax in the hole so that on the assy. line the ball joint didn't spin as the worker assembled it,......with a sprayable Cosmoline you can simulate the dipping by carefully taping off the end to simulate a submersion "plumb line" as if it was hanging on line, runs, drips, sags and discoloration would be the norm along the control arms length in a vertical position
