Thanks cwa107, Pophboi, gibson, samson

questions should I use 2000 grit sand paper wet sanding?

correct me if i am wrong.

1st sand the bumper down
2nd paint it bumper with 2-3 coat of factory paint I am using a spra can.
3rd Wet Sand it down with 2000 grit sandpaper.
4th Spray 2-3 coats of clear coat
5th Wait 4-6 hours then wax the car

 

I was told to sand the bumper down, then spray paint with Auto Primer, then let that dry and use spray paint of color of car...

 

yeah, you might want to consider doing primer first, but if you're just doing a spot? I dunno. Make sure you're waiting the specified drying time before you start sanding anything or dumping water on your brand new paintjob, otherwise you're just gonna get a handful of paint. Lastly, I don't think you actually want to *wax* your new paintjob. this sounds like a bad idea. yes, you can rub it out with compound, but nothing wax based.

p.s. good luck finding small amounts of 2000 grit sand paper. the finest grit I could find in small packages was 1500.

let us know how it turns out.

 

uh, from what we used to do to the cars at the shop after painting and couple of clear coats (wait like half a day), was a Smooth Water Sanding over with very fine grid sand paper, after that, wax and polish.

Oh yea, make sure u're watering and sanding at the same time. DON'T SAND THEN WATER

The part of Wax and Polish was to make the spot's color match with the rest of the car, because you know how new paint job stick out like a soar thumb.

 

yeah, but aren't there certain waxes you shouldn't use?

 

so wet sanding over the clear coat will work for me? I am going to do this next saturday. So more info.

 

1. Sand the effected area down, lightly sand the surrounding areas until you're down to primer on the damaged section and you've taken the surrounding areas down to color coat.

2. Clean the sanded area with a damp, lint-free cloth

3. Spray the area with the color coat slowly from about a foot away, making slow even passes.

4. Allow the color coat to dry, then lightly sand with a fine grit (2000) sand paper.

5. Repeat step 2.

6. Spray with the clear coat, allow it to dry, spray again, allow it to dry and spray it a third time.

7. Lightly sand the area with a fine grit paper again.

8. Lightly buff the area with a rubbing compound

You should be done - it should be shiny at this point. The toughest part of the whole process is blending with the undamaged paint.

Remember that sanding is the most important part of the whole process. This is where you'll blend the painted area with the surrounding undamaged paint. Patience is the key. You'll never be able to get it to look perfect with spray paint, but you can get damned close if you do it carefully.

 

thanks cwa107
Thats what infomation i needed, I know where i mess up it was the sanding part. I ordered a digital camra it should be coming in 3-5 days, I'll take some pictures.

thanks guys

 

Yeah, please do post some pics. I think the biggest confusion people have about painting (generally) is sanding. Most people associate sanding with "roughing up" paint. When you're talking about really fine grit sand paper like 2000+ grit, you're mostly buffing as opposed to removing the paint. What really gets you that mirror sheen is the paint being ultra-smooth.

Like I said, with a little patience and time, you can really do a good job. The reason the pros charge so much for a good paint job is not that the actual painting process is difficult. It's the buffing and sanding and attention to detail that costs money.
