Hai, how to bring back shine on car after wet sanding?

I had wet sanding my car with only 2000 grit sand paper. Now the surface is dull. How to shine it back? Mine is 2014 honda city black pearl.

Polishing compound and a lot of elbow grease. If it's pearl though you have probably wrecked the paint. Better to clear coat it.

Assuming you have a clear coat over your pearl. If so, just get out the cutting compound and polisher…

You need to clear coat it.

You wet sanded a 2 year old car? Take your car to a car body/paint shop so they can finish what you "started".

Polishing compound and a good wax job.

Use rubbing compound on it. Then use Maguire's Mirror Glaze.
