Thanks - I wont be giving up
I'm feeling chipper and managed to finish priming the main unit and the base today:

This U-POL primer is really good:
https://www.amazon.co.uk/gp/product/B0096JWL12/. It goes on lovely. I'll try and get the top coat on the main unit this week some time. This is the RAL902 I've been buying:
https://www.amazon.co.uk/gp/product/B00CXM0UMQ/. To be honest, it's working out quite expensive (probably 5 cans by the time i've finished). A mass-produced colour - like appliance white - would have been much cheaper... or at least I should have got a tonne of 902 mixed up and borrowed a compressor.
I finally managed to shift the old side art (one side only so far):

My fingers really hurt. Got the last of the crap off with alcohol. I'm not even thinking about removing the other one at the moment - need the blisters to go down first

. I'll be rubbing the monitor housing down, filling all the little dinks, and putting a top coat on it.
Other things I'm doing....
I like the look of Hammerite Smooth Silver for the base and ll pick a couple of cans of that up.
I've chased up the reproduction pcb door and hope to have that in a week or 2.
I've found a guy in France who has previously drawn and printed Swing art, so have put an order in.
I've decided to stop keeping track of the amount I'm spending... Nearly there.
