Hi Malt, I got the paint from St Ouens Motorworks
http://stouensmotorworks.co.uk/ It's just before the Farmers Inn on the left-hand side on the way to St Ouens Village from St Peters. Only £6.95 for a 500ml can, best price for the quantity. I used two and bit cans for the forks and frame. They also sell 4 different grades of sanding sponge pads, only 50p each. You'll need some, much better than sand paper on a curved surface. I used the yellow one for flattening off the base coat before applying the lacquer. If you want to see what the colour is actually like before buying, you're more than welcome to pop round and have a look.
Best price for lacquer is at Ernie Le Feuvre's, (Rue de Bechet, Sion), only £3.99 for a 500ml can of Tetrosyl (£5.35 at Corey Car Paints)
