theres nothing wrong with the finish apart from spatters ive tried 4 different brands now all start spitting when the can is half used, i used to work in a paint shop and theres nothing wrong with the way i spray or prep, most the spatters i can sand out but there some pretty large ones and as im using metalic paint the spatters ruin the finish, Ive been told that most metalic rattle cans do this, also i disagree about a pro finish with rattle cans, Depending on what finish you want highly depends on the thickness of the paint also the amount of paint applied with each coat and the angle of the spray these can all be adjusted on a spray gun or air brush but not with a rattle can, rattle cans are made for touch ups and small areas, all the time i spent in the paint shop i dont think we ever sprayed a car or bike with rattle cans and even the old timers had a hard time touching up with rattle cans.
