How To Caste a Prop Engine Block Using FlexFoam® iT! 17

Flex Foam-iT! 17 cures in 2 hours, at which time the expanded foam plugs are cut off using a sharp knife. The Sonite® Wax sealed backer board removes easily from the foam casting. The Mold Max® 25 silicone mold is peeled way from the cured foam piece.

The Flex Foam-iT!® 17 casting (on right) and original engine (on left) are nearly identical in appearance. The Flex Foam-iT!® 17 casting is lightweight and has excellent surface detail. The flexibility and toughness of Flex Foam-iT!® 17 helps reduce wear and tear on the replica engine.
