Steel Seal
 

Clicked on the banner ad for Steel Seal. Anyone ever tried it? Just curious.

nope, but i did use "bars" the one you could pour directly into the coolant with fhushing. i had a small head gasket lead near cyl #8, and used it for a temperary fix (through the summer) it worked instantly to seal the leak and was still holding fine when we torn the dopwn a couple of weeks ago.

I was surprised how ell it worked. i didnt have any leaks into the block, it was to the outside, just an FYI
