I sandblasted my fenders then used the POR-15 without any Metal Ready, just cleaned them real well with PRE or another grease/silicone remover. The POR just seemed to soak into the metal, really good stuff. I did find that the second coat dragged a little due to surface tension. Stuff is hard as nails.

Good Luck.
