Frequently Asked Questions
How do I stop water from pooling near the rear window after a sudden shower?
Pool prevention starts with fit: use a cover that contours around the rear window or a custom fit option so water sheds off the surface instead of collecting. If you can’t cover immediately, dry the area with a microfiber towel and apply a protectant designed to repel water until a full clean and inspection is possible.
Can I rely on a waterproof cover alone to keep my convertible seats dry?
A waterproof exterior cover is your first line of defense, but it must be secured properly — loose covers can allow wind-driven rain to enter seams and windows. Combine a well-secured cover with ventilation to avoid trapped humidity and occasional use of a protectant or interior moisture control (silica packs or breathable liners) for best results.
How often should I clean and reapply protectant to a soft top in summer?
For frequent outdoor use, clean and reapply protectant every 3–4 months, or after heavy exposure to tree fallout or bird droppings. If you notice water no longer beads on the fabric, it’s time to reapply the protectant sooner.
