Caution, Revell paints available in 2 ranges:
Enamels in metal tins, treat like humbrol, as above, white spirits or enamel thinner.
Acrylics in square 'flip-tops', treat as acrylics, thin with distilled water.
((EDIT: I'm sure craig knows this already, but pointing out to noobs that you need to use the appropriate thinner/cleaner for each type of paint. ))
I like their Bundeswehr colours, very '70's-'80's BW
