I disagree. Used it following directions to the letter on the exhaust manifold and pipe for the '64 Ford 2000 series 4 cylinder tractor over a year ago. It looks great at first but within a couple of months, it was blistering and then started peeling off. The tractor gets used maybe once/twice a month and lives in my shop, not outside. For about $30 a pint (if I remember right), I think the stuff is crap.
