Go to a good Body Shop Supply store that sells high quality paint and supplies to shops. Most of them if you give them a paint code, will mix you single stage touch up paint or the color and clear seperate... We have a shop here in town that I use and the paints are awsome; If it was summer I'd have a good excuse to take the Porsche for a cruise to Ann Arbour and bring you some paint
