Next is a very important step, we need a matt finish so I misted on a few coats of Vallejo Matt Varnish. This is important because otherwise the metal surfaces are too shiny and the top coat can wipe off, the matt provides a key for the top coat of paint. With the matt coat applied it’s time for the AK Interactive Worn Effects chipping fluid. I find it a bit too thick to spray neat so I thin it with a little distilled water to help it flow through the airbrush. To accelerate drying, I give the model a blast with a hair dryer. 
Underside…
Using Tamiya XF-76 IJN Grey, the underside was sprayed; you’ll note that various panels and surface features have been picked out in a lighter shade. This helps to break up the large monotone colour but this will be enhanced by oils later on in the process. 
Camouflage dry it’s time for the fun bit, water is applied to the area we want to chip and allowed to soak in. The longer the water is left, the more Chipping Fluid will dissolve and the bigger the paint chips. I wanted the underside to be moderately chipped with the damage being caused by knocks and dings rather than having the paint flaking off so after a few minutes I started scrubbing with a small cut down brush. This makes the bristles a bit stiffer which is ideal and makes the chipping process easier and more controllable.
