Silverguard Plus Material - TOUGH ON THE OUTSIDE, SOFT ON THE INSIDE
Silverguard+ is a 300 Denier polyester material with a reflective, water resistant coating on the outer layer and a soft, non-abrasive layer on the inside. It is a great choice for all-around car cover use, suggested for most conditions except extreme rain, snow or ice. 300 denier is a strong, heavy weave which will not rip or tear easily. The silver coating on Silverguard+ does an excellent job of reflecting sunlight, while keeping rain and animal droppings from damaging the vehicle finish. The special soft inner layer pampers the most delicate paint finish. As with all Coverking Custom Car Covers, Silverguard+ can be custom made in just 2 days.

Car cover maintenance tips:

It is important to keep your cover clean. A dirty cover will actually harm vehicle paint, and will transfer dirt and dust onto your vehicle after use. So take care of your cover. Here's how:
After use, your cover will inevitably become soiled from the elements it was designed to protect your vehicle from. When this happens, wash your cover in a large commercial washing machine. If the cover is excessively soiled, use a mild detergent. Do not dry your cover in a dryer! Hang it out to air-dry.

See G2NMA1210 for a list of all options.
