So I wetsanded a car with 220 grit sandpaper...

Well, from looking at the scratch, it seemed like all I really had to do to level the paint was to use compound and a cutting pad. The customer already has looked at this thread and is happy with the way the car turned out except they were a bit disappointed with the mess-up. I am glad that people can see beyond the mess-up as a simple accident, cause accidents do happen. Nevertheless, I am working with the customer to see what they would want to do with the mess-up...they will be taking the car to a paint shop soon.

Agreed - a quick trip to a local auto parts store would have yielded wet sand paper which should be used on cars
 
xfore- Well, it sounds like things turned out OK. So take this as a lesson and order up some Meg's Unigrit. I keep two versions on hand: 3000 paper and a 2000 block. These won't cut like coarser stuff, but they'll do the job and are pretty safe.



The paper and block came to about $57 including shipping (ordered straight from Meg's) and for that kind of money IMO you oughta go for it. They'll come in handy some day.

If you're not prepared for a repaint, you should never get near a vehicle with anything less than 3000 grit paper.

I would disagree with that as a paper as heavy as 1000 grit can easily be handled by an amatuer and 2000 is also very safe if used properly without fear of facing a repaint. It's like anything, learning the proper procedure is more important than the product being used. :waxing:
 
Wetsanding is not for the faint of heart!



I won't wetsand with anything less than 1500 grit, 2000 is preferred. I have done some minor wetsanding, and practiced on a junk trunk lid I got from one of our auto extrication classes.



Next time, look into a product like Langka to level out touch up paint.

Ya, I'd go 600, 1000, 1500, then maybe even 2000 or higher. Perhaps try polishing at 1500 and see if you're happy with the results. Like the other guys I'd say any sanding with under 600 grit is going to get your through the clear *really* fast, so if you notice the paint is discolored after the 600/1000/1500 polish combo you're likely going to have to get it re-sprayed.

I agree, but you probably need a rotary to correct this all.





Ultimately, you might wanna start looking into a bodyshop.
