plasticote engine paint is crap

I will never will use spray can stuff again. Only good acrylic enamel, and you can get any color mixed. Epoxy primer the block first. You'll never have to repaint the engine again.
More spendy, and I know some of you don't have a spray gun. But it well worth it for the paint, and borrow a gun if you have to.

i've done that a few times also, not sure it works any better than the tractor paint though.
