So I removed all the trim and the decals from the doors and sanded them down. There are like 30+ little chips in the paint from where stones hit the doors. On the first door, I just sanded down to get them as smooth as I could, then I put high-build primer/surfacer over them. They we still visible, so I added a few more coats. I haven't sanded it yet. I'm assuming when the car is block sanded they'll go away?
On the second door, I used a strip disc to take the chipped area down to bare metal. Then I did the same thing. On this door, you can clearly see the areas where I took it down to bare metal after the primer/surfacer dried.
Are any of these methods the right one? Is there a trick to removing a bunch of tiny dings/chips when you re-paint a whole car?
