What are UVR inhibitors?
Most fabrics are degraded by ultra-violet rays (UVR) from the sun. To slow down the degradation process, chemicals are added during the production of the car cover fabric. You won’t be able to see them, smell them or feel them. The chemicals are expensive, so your best bet is to buy a car cover from a reputable manufacturer who believes in quality. To reduce cost, one of the first things a mill will cut is the percentage of UVR inhibitors being used.
