Wow.... what a load of BS.... My tupperware bike is clearcoated 3 times with my new paint. Corvettes are clearcoated (plastic). Toyotas are clearcoated (Plastic)..... Go see how many plastic parts are on your car. Go see how many plastic parts are on the car that the service manager drives. Just more of Hondas BS. Goldwings with Metallic paint are clearcoated. ( I believe that all metallics have to be clearcoated) That is why Honda puts a light coat of clearcoat on all their metallics..
It is a slightly different mix of the clearcoat specs for Plastics. Try going to an auto paint repair shop and ask the same question. Fact is that Honda has been using a water based enamel on solid color paints the last few years that is cheaper and does not take clearcoat, but scratches easily and they are ashamed to admit their mistake. LOOK closely at the pic.... one coat of tinted clearcoat with several coats of regular clearcoat. Have done several 1,000 mile trip since painting....... no scratches, quick wash & dry. And I don't baby it.......
Honda was in a class action lawsuit on their cars from the late 1990's and early 2000's because of a cheap clearcoat they were putting on all of their cars and the clearcoat cracked and peeled <<< those were metal parts not plastics. The new Toyota van in the pic of the bike below is part plastic and part metal body parts..... all clearcoated.
