The paint was at best rather tired.
At worst it could be described as rather tatty and the brass was tarnished.
First thing was to strip the paint using a product called Nitromors, a cellulose paint stripper available in the UK that works rather well. Literally it took the paint off in seconds. I then polished the tarnished brass using a glass fibre pen.
Then primed, painted the red first, masked and applied the green, followed by another mask for the black. Minor touch up work still to be done.
I'm now looking at a re-power solution to replace the massive Pittman 5 pole motor that intrudes into the passenger space.
