Can I wet sand a pearl coat

I painted the Camaro today and was in the middle of the first coat of clear with the pearl mixed in and it was getting quite foggy in the shop so I opened a nearby door to blow some out and the clear with the pearl in it on the front fender near the opened door has a bad sag. Can I cut and buff this or is it going to dull out like metallic? I put two more coats over the top of it after it sagged. Am I going to have to paint the fender over? The pearl was in the clear, if anything I guess I won't have to repaint, maybe just reclear with pearl

Realistically, you can't. Depending the amount of pearl in the clear, depending on the amount of coats applied, it may be able to be repaired. If there isn't a whole lot of pearl, you can cut the run and then apply more over it. But most likely, it will be seen.

You could rebase it, blending out the base. Then re-pearl it blending that out identical to the base you sprayed. Then apply the rest of the coats of pearl over the whole thing.

I have to say, pearl is a steep learning curve.

You said it was a bad sag so I take you can see a discolored area were the sag is if so you will need to respray this panel just block the sag with 800 grit then scuff the rest of the panel then you can blend just like MARTINSR said

The pearl don't really look like pearl, the guy I painted it for picked white base and white pearl but the bottle he picked out says "Mica", is this pearl? I had my doubts about white on white. Where I got the run it didn't "bunch" like metallic so I'll try to sand it and see what it does.

"Mica" is just another name for pearls these days. Did you put it in a urethane clear, or in an "innercoat" clear. The innercoat clear is what the paint companies use for pearl three stages. It is MUCH easier to do than the urethane clear. It is basically a "Colorless" basecoat at that point and very easy to apply.

I just put it in the clearcoat clear but just the first coat. What makes it easier to apply, does it go on "dry" like basecoat?

If I were to look up the formula for a three stage "Pearl white" in a major paint companies data base I would find a formula that would include a base color, and then the "mid coat" color. The mid coat color would consist of tbe mixing clear used in the base colors and a pearl. It is applied exactly the same as a base coat and looks exactly the same.

DuPont had for years in there tech manual a recommendation to simply reduce the mixing clear with basemaker and apply it over a panel prior to painting and blending. It would eliminate "metallic stacking" in the blend. So the use of even straight mixing clear (well straight clear reduced) is often found.

WAAYYYY AHEAD OF YOU!! My wife used to have a nail salon and has a crapload of those little bottles leftover, she has every color under the sun. The bottles she has are only about one teaspoon each so I'd have to do something small. Some are awsome colors. So, Martin, a three stage is just a two stage with the pearl and mid coat clear already mixed for the in between coat (3rd coat)
