  2. Remove any excess sealer surrounding the hinge and scribe the location of the hinge on the body.
  3. Lightly hand-sand existing body hinge with 100 grit or finer sandpaper to locate each weld attaching hinge to door.
  4. Important: Original punch marks may not necessarily indicate the center of the welds.
