I recently finished this fountain for my office. It is the first Moai that I have carved. This particular tiki has a plywood frame that is covered in dry floral foam then sanded to shape then coated with fiberglass resin and mat. To finish this project I skinned the surface with bondo, sanded out MOST of the imperfections and painted him with rustoleum hammered copper spray paint. It uses a small 80 gallon per hour pump that circulates water through his nose and into the mouth. This sculpture was loosely based on the art work entitled "night cap" (sorry I don't know the artists name).
