Sir I hope you don't mind my post, but I really suggest you work on the basics first, for example, "cleaning".
Safai nisf detailing hai sir.
Body work and cham cham paint has no value if the badges have truck loads of dirt, wheels are dirty, door jams show up white, door protection moldings have white stains, door handles have salt deposits around them......
If you learn to clean properly, you will learn how to make the paint shine automatically. Ignore the basics and you'll only end up with a slightly shinier dirty vehicle.
