I'm trying to avoid replacing the top right now because I want to focus my money on other parts of the car. The softop is in good shape, it just has color fade.
I found a solution for this problem IF it's a cloth top. There is a company called Renovo and they make the clear, restorer and repellant. It will cover up the fade but only if it's a cloth top!!
I called the company and according to him, the original tops on the 240SX were cloth tops, not vinyl tops, like most Japanese convertibles. If it's a vinyl infused top I'm out of luck, but it doesn't look to me like it has vinyl in it.
Does anyone know if all of these cars have cloth tops?
