Restoring CJ5 frame. One place says to use epoxy primer with a ceramic chassis black, another says to prime with rust encapsulator then top coat the extreme chassis black and yet one more says use the por 15 products. I’m very confused as to which one is best. I’m going to use the jeep as a driver when finished and although I won’t be offroading with it, I will be driving it in the snow here in the northeast so what ever I use, needs to be able to stand up to the salt and chemicals they put on the roads. Can you please help me to figure out what is best.
