Okay, so I see a lot of chop threads where people have airbrushed the hell outta cars. I'm wondering, how exactly do you do it? Im playing with the airbrush in Paintshop and I'm not having very good results. Same with photoshop. Somebody, plz teaach me the ways

Practice.

Having a drawing tablet helps a ton too... I don't go a day w/o using it.
