I get my aerosols of paint from Kevin Mole Outboards on the IOW. I have got paint for the Yamaha and the Suzuki and the colours have been a good match. I usually get the etch primer, colour coat and laquer. The paint covers nicely. Good service as well.
Ocean Blue up to 1983
Marine Blue 1983-1993
Bluish Grey from 1994 to date
Dark Blue was that blue/purple colour that was used on the Origin range.
