Listen to Grubby. Perfection guaranteed every time. If not, yer kinda stuck with thick black lines for brake lines, hoses, electrical wiring etc. Illustrator is called Illustrator for a reason. You truly create something from nothing. Photoshop is the primo king of all image MANIPULATION programs. In and of itself it can't really do the job properly. Combine the two and you can truly kill....as Grubby has so amply demonstrated in his Sabre illo.
