I have just bought a white I just went for gloss white RAL9010 it's £14.00 a tin off e bay white is white in my eyes
Avenue Coatings in Slough mixed it for me (they'll do any VW paint code). They'll post it. http://www.avenue-group.co.uk/coating1.htm Their paint mixing fellow has done a lot of L90D in his time!
Worth saying that if you're near them (or can post a bit of your van), they can scan it and mix to colours that have faded over the years.
@mollysdad. Did you use combicolour on the exterior. Well 6 years on how is it holding up - any flaking, peeling. Anyone else had CombiColour on the exterior for a while?
