I bought a set of used doors for my 94 4door 4runner to replace damaged ones. It's been 30+ years since I did any body work or auto painting.
Should I prep paint the doors first (jams and inside) then hang them and finish the paint job or should I hang them both and then do all the prep and painting ? Any additional tips would be helpful. (The used doors are white and I will paint cardinal red).

 

Hang them 1st. To get the door gaps set.

You don't wanna scratch the new paint on the rest of the rig do you?

 

If you're painting the entire rig a different color, I would say paint before hanging the doors, otherwise you get the doorjams a different color. However, if you're not repainting the entire rig, only the doors to match the rest of the truck, then hang the doors first.

But uhh... I doubt you can color match doors with a vehicle that has had 13 years of fading

 

put them on, and make sure everything lines up. set all your hinges, anything that needs to be done. Pull off and paint em up. Install should be a breeze after that
