"Hi, I'm Doug I work with 20 great guys in St. Louis at Doug Jenkins Custom Hot Rods and we are going to do some work for your today on Expert Village. First, thing you need to do is prep for paint. We need to prepare the surface, we need to sand it very carefully, fill the chips, sand that filler to smooth and then prep the whole piece in order to get the paint to blend and the clear to stick. First thing we need to do is sand the area very carefully to get some of the shine off the paint, to try to smooth out the damage a little bit. Dan here is the expert on this job and he is using what 200 grit-500 grit. First thing he is doing here is 400 grit sand paper to just take the high spots off and to rough the paint a little bit. You have to keep the sand paper wet while you are doing it or the sand paper would get clogged with the material you are sanding off. You need to keep the water clean. You need to change it often. When you are sanding if you feel something rolling under the paper, it would make a zip sound of something. That means you have some dirt or some contamination under the paper. Stop what you are doing. Change your water throughout your sand paper you don't want to take a little bit of grit and run it over your fresh piece. Then you have to clean it up so you can see what you are doing exactly when it is wet you can not really tell what is happening."
