Some parts I tried to paint as much together as possible. The paint is a couple days old but still not fully cured. I have been using dry powder graphite on parts that touch as a lubricant and to help keep the paint intact until fully cured. So if it looks dirty on the track parts that's just graphite powder.
And assembly is slow as some things need to be adjusted for the layer of paint. I tried to make certain areas loose tolerances as I've herd people say after paint the parts don't fit. I have to finish up the hydralic parts and paint them. Still waiting on radio. As I really don't want to do all that programming just to redo it when radio comes in.
