i have no idea where to start but i want to sand my car and primer it black for now... until i get a paintjob, cause my current white paint is shit. what all do i need? how much does this cost and do i have to take parts off of my car to sand/primer it? what kind of sander should i get, what kind of sand paper? which primer is the best? where should i do this? how long does it usually take? does black primer look good? do i sand the car down to bare metal? as you can tell im completely clueless. please help.
