    I was wondering which would be better for the undercarriage. Rubberized undercoating or black Rust stopping primer?

    I think the black paint would penatrate the smaller cracks. Use both!:D

    That's what I was thinking. The primer would be a good surface for the undercoating to adhere to.

    A lot of people in the classic restoration circles are adamantly against rubberized undercoatings because of their tendency to trap moisture there by promoting rust. A product I have come across recently that seems to get a high amount of praise is POR 15. Some guys think it is so awesome that they will forgo powder coating for a generous amount of this stuff painted on the frame. I personally don't believe it is better than powder coating, but for a body undercoat it is probably one of the better products out there.

    ... It might be a good idea to put some kind of sound deadening undercoat on top of the POR 15 while you are at it. Not necessary but while your down there...
