im going to paint the inner fenders on one of my cars and was gonna use rattle cans as i have done it before and i was somewhat happy with the results but i now have bought a gravity feed gun and a adjustable regulater and a water seperator etc. spent 245 bucks and am gonna give it a try but do not know what type of paint i should use. this is not my first time ive used a spray gun as i painted my motorcycle trailer with a siphon gun but it is a trailer and and not enclosed and it is ok but not perfect. ive sanded and primed (rattle cans,3 coats) and before i sand the last coat i want to be ready. im guessing about paint as i dont know and 3 diffrent paint stores have given me 3 diffrent answers. im gonna paint both sides and this is a experiment by me to see how i can save money and do it myself plus learn how to use this style system. i wont paint a car but you gotta start somewhere. any advise would be appreciated. also it's gotten cold here 40's to 50's and i dont own a shop heater. is there certain temps i must observe? thanks in advance. ps i talked to the guy who is gonna paint the car and he said just bring them to him but then i dont learn....
