I like the idea of Al paint, but this epoxy stuff is really strong. The only time I ever saw it come off a beam, was when the steel underneath peeled off. I can't think of a better guard against salt and rocks than a thin coating of essentially JB Weld with a nice color to it. I think I'll try the Al on some of my tractors, though, be a good look for them.

I figured the PTO was a long shot, but I thought I'd ask anyway. Thanks.
