As there are no stock looking aftermarket door panels available for the '67 Cougar I had little choice but to refinish what I had. They were pretty hammered and had already been colored black previously from the original Ivy Gold color. I wasn't overly enthusiastic about the potential but in the end, I was very pleasantly surprised with how they turned out. I used the SEM cleaner, SEM paint prep and this SEM vinyl/plastic Landau black paint. The key question yet to be determined is how well it will hold up. In the meantime, they look almost new and I'm very happy with the end results. See the before and after pics attached.
