Mike, this is all paint, except for the wheels, which have a black wash. The wide all inserts are painted with white primer. The tires and back wheel inserts are weathered with the airbrush by dusting/fogging a bit of sand and light gray acrylic paints, slightly diluted with distilled water so that they are transparent.
Thank you for the question and comments.
Thanks, D. I appreciate the comments and support.
Thank you, Steve. Stay tuned in for more.
