With the Clay Magic kit I got from Autozone, I went ahead and clayed 2 cars today.
1st car: Paint felt rough, and after claying it felt like glass. Very nice! However, claying didn't remove the water spots like I had hoped.
After claying, I tried (in this order) Meguiar's Cleaner Wax, 3M IHG, and Klasse AIO in an attempt to get rid of the water spots. But they're still there.
2nd car: Clay didn't seem to do much for this car.
The visual appearance of the paint before claying already looked pretty good, but the surface felt dull (non-glassy) to the touch in some areas. After claying those areas, the surface didn't feel any different.
One thing I noticed was that the clay didn't seem to be picking up anything, unlike with the 1st car where there'd be a brownish color to the clay after I clayed a section. I had gone over the area a few times, applying a little more pressure each time. Ah well...must be some other sort of paint problem that claying doesn't fix (oxidation?)
