Permatex High Tack Gasket Sealant: Fast-Drying, All-Purpose, Sensor Safe , 4 oz.

Love this stuff! Used it to tack the new gaskets to my replacement water pump and the thermostat housing. It doesn't take much of this to do the job. Buying the can was overkill but there was no smaller option at the time. This stuff is sticky .. wear nitrile gloves when applying. Don't get it on your clothes because it will not wash out.

I've used Permatex Form-A-Gasket and Indian Head gasket sealer for decades. They are excellent products. I can't say the same for their High Tack Gasket Sealer. I saw it in the store and thought I'd give it a try. It may be good for simple gaskets like water outlets or valve covers, but for more complex gaskets, like some manifolds or water pumps, or in tight spots, you might want to use something else. Maybe I got a bad batch, but the stuff I got is like a cross between contact cement and bubble gum. It's stringy and dried almost as soon as I brushed it on. Lumpy, hard to smooth out. In my case, I was installing a timing cover. It's in a tight spot and you have to twist and rotate the part to line everything up. As soon as a corner of the gasket contacted the block, it stuck immediately, couldn't reposition it. Ended up destroying a $10 gasket. Had to remove everything and clean off the High Tack with acetone. Started over with a new gasket, but used Form-A-Gasket instead, which worked perfectly.
