New to wet sanding.

[slickooz]

I have found some scratch in my new car. I also used touch up paint to cover a small scratch and wanted to know if I can use wet sand to get rid of the touch up paint. What kind of wet sand grit do I need? And what do I use to remove the sanding marks?

When wet sanding aren't you removing some clear coat? Would that mess up the clear coat?

Oh boy, I'd stick with one of the Langka or Dr. Color Chip solutions rather than wet sand if this is your first time and it's a new car. The great thing about touch up laquer and the Langka technique is if you don't like how it looks, you use some solvent and take the whole thing out. Anyway, with that, you can just use some polish when you're done, and you don't have to worry about sanding through your clear or compounding out sanding scratches. Just my two cents.

I just got my car back from body shop today. And I asked them to remove a scratch and it looked very easy. He said he used 1500 wet sanding paper and then used compound to remove the sand paper marks.

Well, I'm sure brain surgery looks very easy, too, but I wouldn't want someone who'd never done it before operating on my new car...or something like that. Did you ask the guy how many scratches he's sanded out on the way to making it look so easy?

As a great guy on another forum said (to paraphrase) when you're going to do something like on a new car etc. that whoever's doing it should have a lot of experience, and that doesn't mean doing it 5 times, that means doing it hundreds of times.

Find a friend who has a beater and ask him if you can sand out some scratches on his car and leave the new car stuff to the body shop guy. Again, just my opinion, but try searching for a few sob stories on here of guys who have sanded through their clear. That clearcoat on your car is two thousandths of an inch thick.

Do your self a big favor and don't try wet sanding on your own car .You need to watch some videos just to get an idea whats involved . After that go to the junk yard and pick up a fender or a hood and practice and practice so more. Post some pictures here and ask a lot of questions. It's a very rewarding process when you get it down but very unforgiving if you mess up.

Thanks. My dad has a beat up minivan, he a carpenter. Which grade of sand paper would you suggest I buy for light scratches?
