Per Schiefler, using older ones over new saves some weight. However those used ones come with a healthy dose of rust.
I've found the chemical rust removers work very well with the WD-40 product seemingly being a better option (faster, but it depletes just as fast) over the EvapORust (found at your local Harbor Fright). Dipping a whole arm only requires a couple of gallons of remover. Which brings me to my question:
With all (most?) of the rust will being removed from all surfaces, is there a method folks are using to paint all of the surfaces (inside & outside) of the arm? What about paint type?
I was thinking dipping but that obviously would require a lot of paint not to mention it going on very thick for the exterior surfaces.
Dipping (to get the interior), then wiping down/squeegy'ing the exterior and hanging to dry?
Then sanding (green Scotch Brite) the exterior and covering with a compatible primer for the top coats?
The top coat I was thinking of the same appliance enamel I'm using on my interior/cage pieces. As it dries harder than other paints but that may not be what's wanted on areas prone to hitting rocks/gravel.
What are others doing short of spending Mazda-level dollars on OEM suspension pieces?
