E booger years back done a artical in Mopar Action about a Rattle coat moly spray. I asked him years later about the application, and part number....
Maybe some one might have that article?
This coating if for a dry startup, engine break in. It goes away pretty quickly after intial startup.
I dont think a expensive coating on the skirts is worth the money, maybe on the top of the pistons etc, but not the sides.
