Pigment thinner, pigment fixer :? confused

[Victor]

Hi i want to add a bit of rust to my tamiya pershing and im not sure what all this pigment thinner and fixer stuff is, i mean cant i just use water to thin the pigments and just use matte varnish to fix the pigments to the tank?

I used a technique of chalk coloring,sealed with Johnson's floor polish then Matt Varnish. This works well to simulate rust in seams and on larger area's like exhaust mufflers and pipes. Sax
