## Questions & Answers

**Q: Do I have to prep the surface since I've used my grill several times?**
A: Yes, the grease and oils from cooking will effect the ability of the sealer to adhere to the surface. I used a spray degreaser and a stiff bristle brush and then finished with rubbing alcohol on a paper towel.

**Q: Is this applied inside or outside the smoker?**
A: Either one would work. The best application is inside the smoker so that the sealant isn't seen from the outside.

**Q: would this seal on a granite counter top joint?**
A: As a contactor that lays counter tops  I'd use a non-sanded grout with a latex mixing compound. It shouldn't take much.

**Q: Can it be used to adhere silacon feet to the grates of a cooktop?**
A: It should work fine as long as it is not expected to actually provide support.
