Old Car, new paint...do I need to remove all paint?

For this Bronco Project, I would:

  1. Give Steve time and talent to get it done right what ever the cost

    20.0%
  2. sand the none-pitted, blast some of it (grill , bumbers, etc)

    20.0%
  3. blast it all

    60.0%
  4. paint remover and scrape it off, follow with scuff and OSPHO, rinse, fine sand

  5. use __________ over the partially sanded areas before priming

  6. Go to the nearest strip joint and hire a stripper to strip paint.

    Do I need to blast or sand off all the old paint? What would be the impact if I only sanded and primed over existing paint? can I kill the micro rust dots without completely removing everything? I have a "shake and spray primer"(it can be returned); will it be adequate under a 2K or 1K paint?
    Current conditions of car and body parts:
    > car is on jacks; weld repairs are completed.
    > removable parts have all been removed
    > The underside and engine have been cleaned and painted.
    > some fiberglass and weld repairs have been completed
    > windows have been removed, a little rust repair is needed.
    > car was repainted maybe once or twice in 50 years. 25 years since last painting
    > old paint is mostly good; some micro size rust dots scattered throughout.
    > seams were rusty have been wire wheeled to bare metal.
    > The front parts (Grill, hood, fenders) have many small rust pits from road blast and beach travels (This is probably the worst of everything).
    > about 6 small dents still need to be worked out.
    > still haven't started on the camper shell (Rust in the cracks under sealer, som front edge damage under gaskets, and a CB hole to weld repair, rusty edges.)

    I plan to make a homemade booth.
    Advise? Please estimate quality versus suggested scope of effort.

    I've worked part time on two early bronco's for last five years. Blast it all. More than likely front/rear door jambs, inner/outer rockers will need to be replaced. If have to replace floors do it with it on frame. Without frame under it the flex is worse than a convertible car. Make sure all gaps are right before paint. The roof probably has rust behind inside braces, under seamsealer at driprail, and across front inside of cap. I cut and glued a piece of sheet metal inside/across front going left to right due to the flex when it gets moved around. They look good done right.

    As far as primer, I use SPI epoxy on all bare metal projects. There is nothing better. If you are going to put time/effort into it you want the paint job to last a long time. A good primer/paint foundation from bare metal is only way to do these early bronco's.
