Review: good stuff - The smell is horrid, but silicone curing usually is. That said it worked great as "gasket maker" for a large broken silicone o-ring on a stainless steel water pipe fitting.
Review: Excellent product, works as advertised! - Used this to fill the leaks around my chimney and fire box on my 15 year old New Braunfels smoker. Thing works like it's brand new. Had been loosing smoke and control of the temperature. Have put about 15 cooks on it since using the product. 6 or 7 big grilling cooks with high temps and the rest 10-15 hour long smokes for briskets, ribs, and pork loins. Used Lavaloc gasket material and this leak sealer, loosing almost no smoke and have perfect control of the temperature again. Looks like my old smoker I almost gave up on, will last another 15 years. Great product!!

## 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.

This was bought to adhere a fridge door seal which would not stop coming off. It works well and the seal has not displaced since the sealant was used.
