did a search and found some good ideas for creating the worn shiny effect. am currently building a tamiya KV-IIA for july club contest (anything by tamiya). also, since this was a cheap buy, am practicing airbrushing using an aztek airbrush and poly s paints for the first time. the build will be for a barbarossa small diorama which will be dueling with a german 3.7cm at gun diorama across the room.
i am thinking that the only continuously touched up (painted) part of the road wheel would be the outside. the rim is steel, not rubber, and i am thinging the axle shaft and the back part of the road wheel (the inner wheel) would either not be painted or allowed to wear to bare steel. except for the rim, that would not be shiny. also, it looks like the support (return) rollers are all steel. track will not be rested up except for maybe some small puddles on the inside as the tank will have been moving. 1it.s a black rubber band track so i will do a steel wash, shine up the wear spots and over wash with some dirt/mud. the lower hull will be muddied up from splashy mud, not thick cacked mud.
