Mod Top

They have the capability to make vinyl top material? And even if they did, where is the pattern coming from?
No, you buy the top in white and have them print on the vinyl just like they do for wraps. Then you install it.

I owned an Auto Upholstery business back in the 80s doing thousands of vinyl tops, and do a lot of graphic art design and printing now using all kinds of materials. I had discussed just this concept with one of my vehicle wrap printers a few months ago and he was sure he could print on a vinyl top.
