Does anyone know what factory brand paint Audi used on the '83 UrQ? Any thoughts on DuPont or Glazurit. Also, did all the US models come with the ring decal on the door or was it an option? One last one, did the 1983 UrQ have just a black pinstripe down the side or was there also pinstriping along the lower edge of the front and rear valences. Thanks for the info. Andrew Finney 1983 UrQ.
