Paint without stripping old paint question

[Curtice]

My current body (FJ40) color is sort of a darkish/turquoise blue color. I need to paint (since hard top, doors, etc. are all different colors). I want to paint it the dune beige color, however I don't necessarily want to strip/sand the whole truck down. I understand you can scuff the current paint, then paint the new color over it.

2 questions:

1. Do I need to prime or seal over the old paint first, or can I just spray right over the old after I scuff it up, and

2. Since the dune beige is a lighter color, is there any chance the blue will show through (or does it just mean more coats)?

Thanks.

To do a decent job you will need to prime over the original paint once you prep via sanding. Do the panels/tub need any bodywork due to dents or rust? If so you will need to apply some type of filler and sand once you fix those areas. Is the existing paint original or has been sprayed before? If it's been painted in the past how many times? The more layers of paint the worse adhesion will be to the substrate. Once you get that figured out you'll want to prime with a 2K build primer or at least some sort of sealer to reduce bleeding problems. The blue color will more than likely bleed through if you're planning on painting it dune beige. There are plenty of paint manufacturers who sell beige primer. I would suggest purchasing some or at least getting a tintable primer so you can color match the other panels you said are all different colors. This is a crash course in bodywork of course. Didn't even touch blocking or wet sanding before spraying down base coat. Oh yeah, what type of paint system are you planning on using? Single stage enamel, urethane enamel, acrylic urethane, base coat/urethane clear coat etc. etc. Their are alot of possibilities in regards to paint. Do your homework and practice on old parts before you start tearing into your cruiser. Even the cheapest paints/primers/supplies will add up and one rule of thumb with autobody is a great paintjob is all about the prepwork. Take your time and don't worry if you mess up. You gotta start somewhere. I sure as hell did.

Appreciate your time. I am still looking into what kind of paint to do, but am not too concerned with absolute perfection since I don't want to worry about it getting scratched up a bit (although I do want it to look nice). The body has one paint job over the original color (white 031), as I can see the white under chipped spots. Not sure about the various panels and doors.

It needs a small bit of body work, but actually not much, I think I can handle it ok for a first timer. I do plan on taking my time and sanding a bunch, just wasn't sure about primer over the original paint, and the color bleed - definately don't want that.

Guess i'll just hit it and try not to worry about messing up like you said. Thanks again. Those pointers are helpful.
