Fran I think it would be fair to say that those of us on here that have a go at weathering are probably at junior infant level compared to this guy. Where as he has earned his PHD. The use of oils, acrylics, gouache, powders, and airbrush that he uses are amazing. Just look at the faded timber on the wagon carrying the rails and the lumps and bumps on the scrap metal wagons. The man is a genius.
