## Questions & Answers

**Q: Do microballoons dry clear?**
A: In my experience, clarity depends on the amount of microballoon powder added. I am using with finishing epoxy, which normally dries clear. To get the consistency I need, there is a slight whitish haze to the dried result.

**Q: volume or mass ?. In planet earth we use to have measurements  "Quart Tub"  really?**
A: Volume.
Canister was full.
Material very light.
Worked well with Poly resin for faring.

**Q: would this work to fix  a snapped surfboard?**
A: It doesn’t have any repair properties, it just adds volume to your epoxy

**Q: Is this hydrophobic fumed silica?**
A: This is not fumed silica, but this also is not a hydrophobic filler.
