<font color=blue>Between anti-seize and kroil, there is no excuse for seized bolts </font color=blue><font color=red>these days.</font color=red>

I first used never sieze in the late 60's when I worked in my Dad's garage. I'm pretty sure he had been using it for quite a while then. We used it on head bolts to prevent sticking and get more accurate readings when torquing the bolts. It works great on exhaust manifold bolts too.
