What is the best way to clean and preserve the frame on an old Jeep when beginning a frame up restoration?

Answer 1

There is a product called POR-15 that is made just for what you are doing. After media or sand blasting you can spray or brush this stuff on and it dries to be very durable. You pretty much have to chisel it off at that point.(You even have to put saran wrap between the can and lid between uses or it will seal the can shut). You can even put it straight over rust after cleaning the metal with a metal treatment. Great product.

Answer 2

Media blast, Magna-Flux, repair (if needed), then powder coat.

Answer 3

powder coat or a very good paint.
