Hi Sprackers
If it is a 3 digit number stamped on the inner wing, it should be the paint code. Option 1 - Some motor factors make up rattle cans of paint for you if you provide them with the paint code. Option 2 - My paint code had been sprayed over when I first got my R4 so I did not have a number to work with. I popped along to a company who make up spray paint for the motor trade. They had a clever scanning device which they used to scan the colour of my paintwork and they came up with the paint code and name of the colour with this device, they then mixed up a can for me.
Best Regards
Chris
