You plan on painting the whole jointer with one can of black spray paint?!?

Phosphoric acid will remove any remaining hidden bits of rust and prep the surface for good adhesion. You can get a gallon of the stuff pretty cheap at the BORG as you mentioned. Dilute 50/50 with distilled water, wipe it on, wait a minute or two, then wipe off. I then like to wipe everything down with mineral spirits just to remove any residual contaminates. Preparation is 99% of painting. And no, it s not absolutely necessary – but you may wind up with a less than ideal paint situation down the road… like peeling paint, or paint that easily chips off when hit.

I also like to brush on the enamel, as it provides a thicker, more durable surface. Primer is not necessary.

Thank you so much, that was the perfect explanation!
Ill head to home depot tomorrow, also, i plan on color matching the jointer and cabinet so i can get as close to the DELTA color as possible.

The black is only for the back of the fence area, and the very bottom of the cabinet.
Can i just spray the paint out in a separate container and then brush it on?

also, what the heck is a BORG?
