The warranty does not cover normal wear, weather soiling, acts of nature, or stains from dirt or pollutants. The cover must be trailered according to specific manufacturer instructions.

This warranty does not cover damage to cover or craft in any form from use of this cover including but not limited to the following acts: misuse, abuse, neglect, improper protection, accidents or acts of God.

Protect your investment by following our care tips for your cover.

  • Avoid letting water, snow or other materials like leaves and sticks stand on the cover.
  • Use support poles, straps, or bows to prevent water from pooling on the cover.
  • Always tie the cover down securely. When trailering, use heavy-duty tie down straps. Avoid using bungee cords that can stretch possibly causing damage to the cover and your vehicle’s finish.
  • Take the precaution of padding windshield, trolling motors, depth finders, etc. before installing cover to avoid accidental tearing.
  • To keep your cover looking its best, regularly brush off any loose dirt with a soft brush and rinse with lukewarm water. To clean, a solution of lukewarm water and mild natural soap such as Ivory™ may be used. Rinse thoroughly and allow to air dry. The use of detergent is not recommended as it may diminish the water repellent finish on certain fabrics and invite the growth of mildew. We also recommend the use of 303 Fabric & Vinyl Cleaner to safely remove dirt and difficult stains.
  • Regular exposure and cleaning can diminish the water repellency of certain cover fabrics over time. The water repellent finish used on most cover fabrics allows water to bead and run off similar to that of a waxed car. When water beading diminishes, we recommend the use of 303 High Tech Fabric Guard after a thorough cleaning to restore the water repellency of your cover.
  • Allow the cover to dry thoroughly before folding for storage.
