The spray paint seems to be a general purpose type thing, here is the UK address http://www.spraypaint.co.uk/ though I am sure its an internatioinal product. I got it from a large retail store called Wilkinsons.
I have just given it 3 layers of laquer, and guess what, got a "run" and couple of hair type things....damnation. Apart from that I am pretty pleased, especially considering the condition when I got it, and that this is my first real attemp...I especially like the bit about saving £100 pounds.
All I have to do is remember how to put it all together now , though I may invest in some copper based paint to coat all the hollow bits (?????), supposed to provide excellent shielding!
BTW, I am afraid to say that you wife does not agree with your last pseudonymn oooopppss
