Try Optimum T.A.R. for rust proofing oil? Works for my just rust proofed Peugeot e-208 GT (yellow & black 😍), but if I'm fast only Opti-Clean is enough but I was lucky with the weather, the "oil" seemed to dry up fast when the sun was shining. I did get some wet and dry small towels to deal with the rust proofing stuff. Paint prep could also work? I always also use a towel that I can throw with either Opti-Clean or ONR and add some sealant as protection becaus it is then easier to clean.
