I just airbrushed rim scuffs and my windshield trim and have a perfect match from local PPG paint dealer. He used a scanner on the window trim to get a match. Here is what it turned out to be based on his scan:MFG Honda, Brand Code 3HTMB, OEM Code NH411M, CMO499, FORCE SILVER, Basecoat, Clearcoat. Used Clear coat rattle can then when dry, buff pad, 1200 wet and 2 buffing compounds. All by hand. Before I put on the car will do a final buff and wax. The silver is a little hard to shoot as there are 3 sizes of metallic in it. Cant be sanded so final coat must be an even spray, probably easier with a rattle can than an airbrush. Might be able to match the honda colour and buy a rattle can at an auto parts rather than get one mixed. I did the airbrush because that is what I know and I wanted to learn basecoat clearcaot procedures before I get into stone chips etc on the body.
