I use Raggtop products for my vert top. They sell products for both vinyl and fabric. I've only used the fabric product and it works great. You use the cleaner first then when rinsed and dried, use the protectant. For the protectant or any of them, be sure to cover areas you don't want the product touching. It won't ruin anything but its annoying to clean up. Once done, the water beads and rolls off very nicely. Lasts at least a few months.
