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. | ||

As a general rule, weld-through primer is applied to the mating areas when welding body panels. List a few commercially available weld-through primers here. 3M, U-Pol, etc. It doesn't burn off when welding. | ||
