Step 1 Rasp or sand the face of the Corner Mount Converter to remove any wax.

Step 2 Position the mannikin with the backboard facing up (a big garbage can will work.)

Step 3 Spread a thin mixture of Bondo over both surfaces. Press them together and allow the Bondo to cure completely.

Step 4 If necessary, rasp any excess foam. Use mache, clay, or Bondo to fill in and match the anatomy of the mannikin.
