Re: do you wet sand/sand after primer? (1.8)
Spray on your primer, let it dry for at least a day. You will be able to feel a texture in the primer.
Run water from the hose or faucet over the piece and sand it lightly w/ 400 until all the texture is gone. Go over it again lightly with 600 grit.
Let that fully dry then spray on your paint, however many coats it takes to fully coat it. After that spray on your clear, however many coats you want. If you intend to wetsand and buff the clear (to really make it shine like glass) I would suggest between 3-5 coats of clear.
After the clear, it will have that same bumpy orange-peel-like texture that the primer had. So now after you let that dry for at least a day, go over it under running water w/ some 1200 grit, and finish up with 2000 grit.
Finally use a good buffing compound like that from 3M, then polish, and then wax.

Patrick. too many useless steps.
Primer, wait till it drys, run water over and wet sand with 600grit. I really don't know how to explain how you should know you wet sand enough. But if you look at the primier at an angle, you can see the smoothness. Can't really feel it.
Now go paint your car correctly and dry it in an oven for 20mins. If you did so, you won't have to waste time wet sanding the clear coat to get rid of the orange peal.
There's a real reason why Dupont painters paint the car correctly the first time. Time = Money.

yes soo true.. so many people look over baking the car man but you put it best when doing the body, Time is most certainly = Money.. I like how you found that qutoe about Dupont guys 
thats true also, many of the Dupont painters i know are rolling in the doe over the PPG guys in my area, b/c they charge a lot and their paint jobs compared to a PPG paint job is Secon to None.. i have seen it countless times that Dupont Clear is Killer.. but yah most of the Dupont guys in my area deal with the higher end folks BMW, Mercades, Ferrari, Porsche etc so they charge more then the PPG (it all pref. really if you know what your doing, but the DUPONT CLEAR, i dunno its crazy stuff).. but enuff of my rambling LOL i just liked the qutoe about Dupont guys..

Useless steps? I don't think so, if you want the best finish.
And when the finish is not shiny (i.e. primer, flat finish), it's ALOT easier to find imperfections by feel than by sight. It's VERY easy to tell where you've sanded and where you haven't by touch. For very small dents and stuff, it's pretty much impossible to see it if the surface doesn't reflect any light, so you have to go by touch. When we were taking the dents out of my car, after using the tiniest amount of filler and primer, we would then sand and then run our hand along the area to make sure it was straight and the imperfections were in fact removed.
And my friend who painted my car, he said at the car dealership where he paints cars, usually they just go over the whole car with 320 prior to painting. Like you said, time = money, and they're trying to get the cars in and out. But with my car we did 400 first, and then took it a step farther with 600 to ensure that all the primered areas on my car as well as all other areas were as smooth and straight as possible before spraying the base and clear coats on.

Start with 1200, then go up to 2000, then follow with a buffing compound to remove the "haze" left by the 2000 grit paper and make it shiny.

Not if you put enough coats on it. When my friend painted my car, he sprayed about 4 coats of clear on it so that the clear would be at least 3 coats thick after the final wetsanding and buffing.
