K9 Weathering

This is always my favorite bit, giving the build its character. Most of the K9 builds I have seem on the net have had very poor weathering and fake rust added, hopefully I will be able to do better and the overal look when finished will be a very used and well traveled K9.
The usual paints are used for the weathering, acrylic paint and the rust and dents applied with flexible wood filler.
