Review: Great - works really well - This is a great product. Slightly scary instructions but we found that there were minimal fumes etc. We've made a number of squishies using this. The only trouble is finding suitable moulds to make them from.
Review: 5 * - Amazing product, making squishies and fake baked goods :) shame the postage is so steep on an expensive yet small purchase

## Questions & Answers

**Q: Would this be useful for encasing a pc to transport? I intend to shrink wrap the PC and foam it in a box.**
A: You would need to pour the foam around a shape that you wish to replicate. Once set, this will produce a very flexible, soft foam. If you would like to see some cured samples, please email us at the email address on our website.

**Q: Can you add colour to this foam?**
A: Yes, as long as it is a Polyurethane pigment .

**Q: Does the mold need to be filled all the way? I plan on doing Predator Dreadlocks.**
A: No, as this is an expanding foam, it will expand to fill the mould. The expansion rates are available to look at on the Smooth On Website so you should be able to work out how much product you need to put in. As with everything, we would suggest a small scale test to ensure that you are happy with the outcome and to get to know the product.
