So, it has finally been finished...
My original plan was to gently remove the Southern Pacific lettering, but that removed the paint as well! So a repaint was in order. Washed, scrubbed and dried, then the primer went on. Flawless. Then I tried a chrome spray. Disaster. Orange peel everywhere! So that came off. Primed again and then using Revell Silver and I was finally happy.
I am now extending the layout to accomodate a passenger service.
