paint problem need help please

It'll be the number of coats of clear over top the flake and pearl that is the important number. If he shot 4 coats of clear overtop the pearl and flake, than cut and buffed you have about a little more than 3 left on the car. Which should be plenty to cut and buff again. It would be preferable to sand and reclear....but that's going to be dependant on how much more money you want to spend.

Yes, you can sand and reclear, there should be little to no chance of it sinking into the paint. Don't skimp on clear, everytime you polish your car you slowly work your way through the clear, everytime you polish a scratch out more of it goes. The more clear you've got on there(to a point) the longer you can keep your paint job looking shiny silky smooth sexyness.
