## Questions & Answers

**Q: Can this be put under radiator without fire hazard?**
A: I used this product in May. It worked very well. I was worried about the radiator in the home because that's where I put most of it. So far no problem but it did sit and harden for 5 months.

**Q: Does it have a smell ?**
A: Didnt notice any smell. Used outside though

**Q: Can you use the can upside down**
A: I didn't need to have it upside down, but I definitely had it sideways and it filled crevices great.  If upside down is a problem, try sideways and use your free hand to point the end of the straw where you need it.

**Q: Found a gap between siding and wall pointing downward.  Mice climb up and get inside.  Will the foam hold up and not get pulled down by gravity?**
A: The foam dries very hard!  I don't see how mice could or would eat thru all of that!  But maybe I would be surprised at what mice can do!  I have an unfarmed 40 acres next to me so there are many mice in the field!  I had to hire a pest control service to put bait boxes in different areas inside and out!  It's costing me around $40.00 a month!  I didn't have mice in the house until I had a walk in tub put in!  They did plumbing under the house and things were not sealed up tightly, so hello mice!
