i paint a little and yea i would charge 2-3 grand for a whole car if it were a show finish because of the work that goes in it. the most time consuming part is the prep. getting the surface perfect before spraying is key for a nice paint job. spraying isnt really that hard, even pearl and stuff, its not that hard to make it look good. add to that some 7-10 coats of clear ( i like it thick) also with out a controlled environment orange peel is bound to happen. then hit it with some wet sanidng and polish and you wont believe what you can do. but anyway if you want to paint your car spend good money on it and 2-3k is the right amount. they wll pull glass, trim, and if your motor is pulled they will do a good engine bay too. you cant expect much for a grand ;)
