since I do upholstery, I guess I can help you with this one. Most vehicles have either vinyl or cloth interiors.
You will want an automotive grade vinyl or fabric at the very least.
I use marine grade vinyls almost exclusively. The reason is that they are more resistant to UV rays and weather. ( A real plus in a rag top or roadster).
Automotive vinyls and fabrics are designed for hard wear and hard usage ( within reason).
If you need more info, feel free to PM me about it. NOTE: I am not trying to sell you an upholstery job.
