:thumb: The cars look great. I have done a few cars and yes there is a learning process. I started on cars that I do not worry if they come out looking like mistakes. I have read in the mrr magazines and forum's post on weathering. I have bought the materials to do weathering, chalks, paint, etc.
I live right near a secondary and yard and the cars weathering and the rust, etc are not the same so mistakes might come looking very interesting.
