does what it does

I purchased this caulk when my grill began to leak grease at the bottom of the barrel all over my concrete during every cook. I recaulked the inside of the barrel. So far so good.

Great product, a little hard to apply

Worked great in sealing my Rec Tec. You need to make sure it is at room temperature or above to allow for easy for dispensing from the tip.

Increbile hi temp gasket maker.

If you are looking for a gasket maker that can handle the hi heat Associated with smokers or grills. This product delivers. I like the red color aswell.

RTV Caulk

Work just like the REC Tec salesman said it would. Great way to reseal the barrel on the bull.

Worked as expected... sealed the 680 right up where the original caulking had peeled a bit. Piece of cake to work with.
