the phone number is 01226 203608, just phone them and tell them you need some paint to touchup your bikes engine, give them the make,model,year, the person i spoke to was very helpful (can`t remember his name!).
the paint comes in a small bottle (30ml), with a small brush fixed to the screw top (the next size up is half a litre or a 400ml aerosol, which is to much for me).
i ordered the paint, primer and laquer (which also come in the same size small bottles), they are �6.00 each. with vat and p+p it cost me �30. ordered it on a monday evening arrived wednesday, the paint is quite a good match, just don`t try and rush it as i did on my first go.
