I has two fuel line fittings that wouldn't stop leaking. I applied this sealant as per the instructions and on the first try both stopped leaking!

Did a head replacement. Used this on bolts and most gaskets (not head gasket). Seemed to work well.

Jamestown should put items like this in a separate plastic bag AND tape around the cap of the bottle.

While the product is very good the packaging was not. This is some very sticky stuff and despite the extra little flap of tape that JD put over the cap it still leaked all over the rest of the contents of my package. Either order this product alone or only with other products that can be wiped off with paint thinner or solvent.
