I was looking over the Tools & Tips Section and came across Kaan Gok's article about painting wing tip lights. In the article he describes a "Faber-Castell transparent permanent waterproof acetate marker." What exactly is this thing, and where can I find one? I went to Faber-Castell's website but couldn't find anything. I'd e-mail Kaan directly, but I'm at work. Any help would be appreciated! Tim
