tried wet sanding......(edit) and suceeded!!
ok.....so we have these parts cars outside...
And i thought i would try to wet sand them.....
hahaha man do i suck.
the first time I tried I used 400 then 600 then 1200
and i stayed in one spot to long......with the watwer on it it looked awesome!!! but when the water dried it looked like ****.....then I tried without 400....it did the same thing.
so I moved on to out red car...I sanded withjust 1200 for like 1 sec with tons of water in one spot at a time.....and I still went through!!!!
what am I doing wrong?!?!
(edit) I just finished doing the upper part of the blue car's door with just 1200 and It looks awesome!!
Now i just need some finer grit!
thanks ya'll.

Wet sanding will not bring the luster out, you need to wet sand and then polish to get the results you are looking for.
But I'd also say you don't need to start with a 400 grit. The last time I wet sanded (and i'm still learning) I used 2000 grit, working the section till it was very smooth, then came back with a polishing compound to bring out the shine.

Yeah, start at something really fine, like 1000 to take off just the tops of the orange-peel. Work your way down to 2000. Then use polishing-compounds.
Also the tools you use is very important. Do not sand with just holding the paper by hand and do not use a small rubber block. You need a stiff long 1/3rd sheet file-board sander. The large surface keeps the pressure even and spread out over a area for an even finish. Better to get the air-powered ones like this: Pro Sander
Then how you use the tools is critical. The pictures above shows different results. The 2nd one is easiest to see and it shows too much pressure and too slow movement (spending too much time in one place). This results in uneven sanding with motion lines apparent. Use a lighter touch on the tool and move it quicker with lots of water.
Another critical factor is the time you spend on each step. The sanding itself is quick, like 5 minutes for the rear fender in the previous pictures. The 1st picture shows taking off waaaay too much material, the 2nd is about right but needs to be more even. Then the polishing itself is about 2-3 hours using finer and finer grits.

400 grit? Are you wet sanding or stripping?
There are tons of threads on this, why not try reading one of them.

wet sanding isn't easy. too bad it's taken me 32 years to figure that out. and you think the sanding is hard? try polishing. you really have to be careful.
i'm going to add something about polishing since most of the above is about wet sanding. the polisher will make your finish look great, but with improper technique can also ruin your finish. use the correct polishing compound (not a rubbing compound), and go carefully. you will cut circles in your paint very easily in very little time. if done correctly at slow speed, however, polishing looks great.
