The final detail parts for my Rock Island Geep project arrived in the post this week so I was able to finish the body shell and begin the painting process.
As per the prototype this GP7 is fitted with tall MU cable stands and spark arrestors, as well as the usual handrails and other details.
I had to trim the exhaust stacks from the shell in order to fit the spark arrestors.
The Atlas cab has slightly different positions for the handrails so I drilled new holes and filled the old ones with squadron putty.
I hit a few snags with the painting, it took me three attempts to get the primer onto the shell, the paint kept clogging the airbrush and I was getting really uneven coverage. I use Vallejo acrylic primer which I have always got good results with in the past but this was a new bottle and I'm not convinced it has not been affected by something in storage. I will need to order a new one.
For the maroon I'm using Scalecoat acrylic Rock Island Maroon, but I'm not entirely happy with the colour, it's probably a closer match to the earlier units, I think I needed more of a scarlet shade for the unit I'm modelling.
I also ran into a lot of problems getting even coverage on the shell, especially in the corners of the hood and cab, where I just couldn't seem to get a decent even coat. I do plan to heavily distress and weather this engine so the maroon colour and patchy coverage probably won't matter too much but I definitely need to work on my airbrush technique for next time!
