## Questions & Answers

**Q: Can this product be sanded down and painted after it cures?  Will this product stick to metal?  Is this product water proof?**
A: Sanded = yes.  Painted = Do some research on painting of foam and check the Smooth-On website for more info.  Stick to metal = Yes.  Water-proof = It is not a foam for nautical use if that is what you are asking.

**Q: is this for molds?**
A: Pouring final products or to make molds either works

**Q: putting in a gypsum cement mold will vasiline work for the release? thanks**
A: No, Vaseline won't release the foam from the gypsum. As long as your mold doesn't have a lot of convolutions and/or undercuts, you can get good results from sealing the mold surface with 2 or three layers of shellac and using a mold wax to release the foam.

You're much better of casting this foam in silicone molds.

**Q: When put it in a silicone mold and wait for it to dry, it hardens. I want it to be soft. Is my measurements wrong or am I buying the wrong series?**
A: Hi, I too ordered the rigid by accident.  I still need to return.  We now have the flex foam 3.... this is the kind you need.  My daughter makes "squishes" with it!  Glad to have helped since I just went through the exact same thing!
