I had to repaint 3 of my basement doors and part of the front slide after my wife hit a pole at a filling station. I have a 4 color paint scheme, 3 shades of green and 1 black.
I got the paint codes from Monaco and I believe it said they used BASF Diamont paint. The paint is a 2 part system, you will have to buy a hardener and possibly thinner to spray it correctly.
The paint job turned out very good (for an amateur) color match was perfect.
Here is a link to the BASF distributor locator.
