stopped the leak
After doing quite a lot of research I decided to give this a try. I have an old Speedaire air compressor that had a leak from the valve plate gasket for which a replacement is no longer available. The gasket is subject to high compression and excessive heat. After attempting to make a replacement from gasket material (which nearly worked but still leaked minutely) I assembled the compressor using this product and it has performed flawlessly: no leaks. It is critical that the mating surfaces are extremely clean before applying. It does set up to a thick gel consistency but it does not harden which many other products do. A bit more costly than many other sealants but worth it.

Luv this stuff
You gotta have the surfaces clean & it helps to use alcohol on the final wipe, but this stuff works.
