    Each allow advantages depending on the application. If you want "production" numbers... and are smart in how the molds are made... resin / epoxy could do great numbers.

    BUT.... as SEALSKINNER stated... RTV could provide higher levels of detail... and intricacies. Remember.... its flexible .. and can stretch a little while your removing the molded item.

    Advantages either way. You need to decide... for fun.... or money. Either way....Good Luck.

    Really clean molding can only be achieved with the use of a degassing machine. It mixes your preferred product under vacuum and without stirring, so no bubbles.
