To do it right, you will generally need to pull the seam apart, remove the rust, and then hit it with a rust conversion product. However, sometimes you can open up the layers slightly with a hammer and putty knife used between the spotwelds. Bend the flange open, media blast into the seam, clean, prime with epoxy primer, brush in urethane seam sealer, and close the seam back up. If the seam is not accessible, flood it with a penetrating cavity wax, like 3M's Rustfighter. | To do it right, you will generally need to pull the seam apart, remove the rust, and then hit it with a rust conversion product.
