The rubber bands are the ultimate chris,There easy and quick to take off,I might ad I cut some wood blocks the size of the mold and sandwich them then wrap the bands around,Over time you,ll find if you dont the bands will cut into the plaster,chip it and it also cuts the rubber bands,i cut the wood from 1/2 inch stock and rounded the edges as not to cut the bands,You can find some nice large rubber bands on some of the plaster mold sites for yard ornaments and such,thats all they use for their heavy molds and they are of better quality,Higher rubber content and will last a long time,You can even find them on ebay once and a while,youll find the cheaper brown bands dont last long,get the large red rubber bands:)
