Thanks . After the mold was built I put a clay radius in all the corners. I made my own fillet tool with a couple different size aluminum balls off of ebay and a piece of threaded rod. Cost less then $10 to make. It worked great. I would use a torch to heat it up a little and it smoothed the clay out perfect. Next I waxed I put like 4 or 5 coats of Partall paste wax in the mold then a few layers of PVA.
