Just a quick note to let UK users who might not have known, B&Q can mix any colour, via the hand held scanner, or by RAL number. I just got some RAL7011 'Boeing Grey' (it looked a closer match than the panel I took to be scanned) and it matches my Engravity MIP exactly.

They do a variety of paint types, I went for the solvent based Eggshell that is good for wood and metal. Minimum quantity is 1 litre, but it only cost 12 and will last me for ever.
