You'll have to add a decent amount of glitter and it will take longer to cure. **Q: Can I use this to cast a dome-shaped mask using a silicone mold? Will it stay liquid long enough for me to tilt it back & forth to form an even coat?** A: Smooth-Cast 300 is a snap cure material - a better choice may be Smooth-Cast 325 or Smooth-Cast 65D, both of which have a gradual cure profile. **Q: is it machinable?** A: Yeah, to an extent. I’ve taken a dremle tool to casted plastic to sand down parts and remove unwanted flashing that occurs. It’s pretty tough stuff, let it cure for a day or two before sanding or working on thinner areas, but I’ve even taken a hacksaw to some castings and they have held up just fine. **Q: Is this a silicone or a urethane?** A: This is a urethane casting resin. ## Frequently Bought Together - Smooth-Cast 300 - Bright White, Ultra Low Viscosity Liquid Plastic - Gallon Unit - Smooth-On Mold Star™ 16 Fast Platinum Silicone Rubber, Silicone Mold Making Kit - Pint Unit - Smooth-On Universal™ Mold Release Spray, 14 fl. oz.
