Super Baldiez is a great product from Mouldlife which can be used as Bald Cap Plastic (so you can make your own bald caps!) and for encapsulating Platsil 10 appliances. Super Baldiez can be blended into the skin using 99% IPA (similar to how other bald cap plastics use acetone.) What's great about the Super Baldiez in particular is it gives you a bit more time to create your bald caps, while also being stronger and clearer.
