K frame refinishing and rebuild advice

Por 15 seems to smooth out really good even using a brush...I just painted all my control arms, spindles and lower control arms and not a brush mark or run anywhere...I droppes a lower control arm on the concrete from 4 feet up and didnt even scratch it...tough stuff here....but like others said its $30 plus for a pint....but it goes a long way...I completely covered the floor of my dart from firewall to rear seat area...plus all the suspension parts with a little left over.
I plan on doing the k member and other stuff too with it even if I have to buy more...oh and follow directions to a t....trust me...if you get a little in the rim and put the cap back on you are not getting the lid off....:-D
