After a bunch of digging I came across a GM service bullitin on chassis repair. It went to explain what was used as the hard wax coating OEM for GM & Ford. It's made by Daubert Chemical & they do sell to the public. It is for new clean metal as a preventive not for over rust applications. Their service rep said 1 spray can would do a frame I ordered 2 & will get the axels, springs ect. on my new 2014, hope it's enough. Here's a link to what I found: http://store.daubert.com/mm5/mercha...OD&Category_Code=Noxrust&Product_Code=1786061
