I guess it would be the same or less resin. I am not really sure. I have now started using two or more layers of 6oz cloth top and bottom on the sand molds. They really do not come out that much heavier than a standard mold as long as you dont go crazy and build it up too thick. There are no problems with getting the sand to wet out properly and there are no air pockets as the wet sand is packed down onto the surface and then rolled out to level the outer surface. I will be doing all of my molds this way in the future. I bet if you were to mix chopped glass fibers into the sand it would be much stronger.

A mold maker here in town told me that my molds would delaminate using this method due to the dis-similar materials used? I thought glass was made from silica? I have not had any problems yet.

Thanks Ted
