Permatex is the good stuff, of course. There's just one design flaw: the nozzle clogs after one use. In other words, you'd better use all of this in one sitting, or the included nozzle is useless.I used this to seal my valve covers, and there was a week and a half between uses (hey, I'm a working stiff and this is a tough repair -- I can't do it all at once!). The first use was great; I was able to use the nozzle to put a bead of sealant near the front cover seal, as recommended by FoMoCo. But the next use, the nozzle was one solid lump of sealant, and I had to ditch it and just use the tube directly. It still worked, but it was less precise than the first use.Otherwise, the sealant itself is good stuff, I think (time will tell!)
