Soft Top Window Restoration

[cpavelko]

so I've had my soft topper top for about 2.5 years now and I've probably left it uncovered longer than I'd like. currently my clear vinyl windows have started to dry out and become opaque. I was curious what products that everyone has used before. What works well and what doesn't.
So far I've seen the Diamondite kit

And The Novus Plastic Polish Kit.

These kits don't mention using a buffing wheel at all. I would think using a wheel with the recommended polish would help.

Let me know your experiences please
