Wet Sand and Clay Bar are not the same......If you never wet sand a car, do not try it on your Corvette.
Wet sanding on a car is very important if you want to get that paint to look it's best, having a glassy smooth look and feel! Wet sanding is meant to flatten and level out new paint, remove small runs or sags, remove surface debris that landed on the paint while it was wet, flatten out orange peel along with minor pot holes, which are called "fish eyes," within the paint. After your surface is nice and smooth from your wet sanding you will need to apply a fine rubbing compound to bring the paint color back. Compound also serves to flatten out paint that may have been missed by wet sanding. Work with the compound until your paint is nice and flat and has it's shine back.
Work the 1000 grit with light pressure over any prominent flaws in a level smooth motion, dipping your block and misting the surface often, keeping it wet at all times. To see where you are at wipe the area dry with your soft rag and work your way to finer grits of 1500 for instance, or even 2000 for final sanding over the entire area after flaws have been removed with the coarser 1000 grit which is most likely to leave sanding marks.
Clay bar will remove any oxidation or overspray that you may have on the paint. Clay is not a cure-all or a replacement for polishing. It's a tool for quickly and easily removing surface contamination. One of the many reasons for using a clay bar is the removal of brake dust. Brake dust contamination, which attaches to painted rear bumpers and adjoining surfaces, is a metallic surface contaminant that can be removed safely and effectively by using clay.
Menzerna offers the most gentle detailing clay available on the market today. Menzerna Detailing Clay removes light to moderate contamination with very little effort. Its very low abrasive content reduce the chances of scuffing even the softest paint finishes. Clay is also very effective on paint over-spray. If the over-spray is particularly heavy, you may want to seek the assistance of a professional. Tree sap and tar specks can also be safely removed with a clay bar very easily.
Recently, I have also started using clay on my windows (exterior) to remove heavy road film, bug deposits and water spots. It works very well, and seems to outperform even the best window cleaners.

All I can say is "Claude-Van Damm that looks nice" I wish I lived by you. I'd pay to have my car look like that

I wouldn't consider wet sanding a car myself. I also wouldn't consider using a buffer UNLESS you know what you're doing. Ever seen a car go by that been 'buffed' improperly by the owner? Swirlies everwhere....
Clay bar is very easy to do. You'll be amazed at the junk you get off your 'clean' car. I realize you are asking about scratches however.
You can definitely clay bar the car and the results are amazing....my two cents....
