When building my -8 I wanted paint to match the powder coat color exactly, so I traced the manufacturer with Van's help. It's Cardinal Paint at
www.cardinalpaint.com and you can order paint to exactly match the powder coat color if you like. They have locations across the country and will also ship orders.
The powder coat part number that matches RAL 7035 is T009-GR230. Van's choice of color was a little on the light side for our taste, so we ordered one shade darker to belnd with our leather seats - I got Van's to ship the metal parts uncoated and had them done locally with P008-GR230. Admittedly a little obsessive, but the results were fabulous and the paint from Cardial was an absolutely exact match since they make both products.
Happy spraying,
Phil Smith
