How To Mold & Cast An Alligator Snapping Turtle
Step 3: Applying the Support Shell
Determine the location of the parting lines and build the shims to separate the mother mold sections. Apply two liberal coats of Mann Ease Release® 200 and Sonite Wax® to all surfaces.
Put the first layer of 1-1/2 oz fiberglass mat on the original. Wet with polyester resin and press in with brush to remove air bubbles. Apply a 10 ounce cloth and wet well with resin. Finally, put the last layer of 1-1/2 oz mat in place and wet completely.
You can also use Plasti-Paste™ II urethane or EpoxAmite™ epoxy with fiberglass mat for a support shell.
