I'm getting ready to go out, and repaint my spoiler, becuse it looks as though it has been painted b4, but they did a real crappy job. I have the sandpaper, primer, base, and clear coat. Any tips... I'm going to be doing this once I get my food and **** eaten then I'm out to the garage...

1) Wipe spoiler off with alcohol or wax remover.
2) Start with a 400, then 600, then 800, and then 1k if you want a nice smooth surface. WET SAND IT!!
3) Wash it real good, then go to step 1 again.
4) Spray with 1 color primer, a few light coats will do.
5) Spray with a contrasting color, mist it on but dont let it cover everything.
6)Go back to the 800 grit, sand. Wherever the contrasting color is left, there is a low spot. Take some Bondo and fill.
7) Go back to step 1, repeat all steps until you get no contrasting color left
8 ) Spray your smooth spoiler with some adhesion promoter, and then do your base/clear.
9) Let paint cure a week, then wetsand w/1500 and 2000 grits...polish out with fine compound, then wax.


Doing these steps will make your rattle-can job NOT look like a rattle-can job, which from what you just said, you are trying to avoid

I didn't go through all those steps, but I did do some of them... I messed up on it so it looks like crap, but its ok... it is a hell of alot better looking than it was before.
