I want to make a landau vinyl top. I also want to add the landau bar. I know how to do this on a real vehicle, but in 1/25 or 1/16, I'm a bit confused. I want to make it the thick padded roof. I was thinking of covering the roof in a layer of sheet plastic and grinding out the space for the landau bar then covering it in masking tape. Any other suggestions? or can this work? I have a photo of a KW K100 with this roof(custom).
