Frequently Asked Questions
Can I use a full exterior cover on a convertible with the top down?
You can, but a full exterior cover may trap moisture if ventilation isn’t adequate and can be bulky to install frequently. For short stops a convertible top-down cover or a lightweight interior/top-down protector is more convenient; for long outdoor storage a full cover with vents is better for overall protection.
Are these iCarCover models fully waterproof?
The covers are advertised with waterproof or weatherproof materials and waterproof-lined seams. In real-world use customers report excellent protection from sun and light-to-moderate rain, though a few users note that extreme, prolonged downpours can reveal seam or fabric limits—taping seams and additional drainage can help.
How do I avoid scratches when using a car cover?
Choose a cover with a soft inner lining (cotton or fleece), keep the car clean before covering to avoid trapped grit, and avoid sliding the cover on and off. Model-specific fits reduce movement and flapping that cause abrasion, and ventilation helps prevent moisture-related damage.
