Hello everyone. Can someone tell me what the finish of the underbody of a Porsche from 1969 should be like in Europe? Some told me it should have a black undercoat, some told me that it should be painted the same color as the body of the car and some told me that there is a special material that is used. If that's the case, can someone tell me where to I can buy it online from a website in Germany?
Also, I heard that in some countries they measure the mils or microns of the paint and in some it doesn't really matter? Can you guys tell me for 1963-1975 911s in your country how important
