I about a 56' Ford F100 a couple of weeks ago thats in great conidtion minus the exterior paint. There's no rust, it just needs to be repainted due to being faded from sitting in the sun. I was wondering if I could spray a flat black over the current paint if I gave a good sanding? It's not going to be a show piece, more of a weekend cruiser.

It depends on what type paint is on the truck. If it's lacquer,
then it wouldn't be advisable to recoat without stripping.
Try rubbing it with a rag wetted with a solvent, and see if the
paint comes off; if so, then it's lacquer.

If the truck has been painted with enamel, then you can do the
body work, sand the existing paint and recoat it with an enamel
or urethane. Not the best way, but it's done everyday.

I'd paint it with a satin black instead of flat. Just my opinion but
satin looks better to me....
