Detailed Description
Simply spray on and wipe dry to restore color and luster, repel stains and prevent fading even in the harshest marine conditions and sunniest climates. And because it’s 100% free of grease-producing silicone oils and petroleum distillates, Aerospace is safe to use on all your outdoor materials—vinyl, rubber, fiberglass and more.
Features:
- Safe and effective for: vinyl, Plexiglas, carbon fiber, rubber, plastics and finished leather
- Powerful UV blockers prevent fading, cracking and premature aging
- Easy to use: Simply spray on and wipe dry
Usage Directions:
- Use only on clean surfaces. For best results use 303® Multi-Surface Cleaner.
- Place a drop cloth under the cleaner to be treated to catch any over spray.
- Out of direct sun, spray surface with 303® Aerospace Protectant and WIPE COMPLETELY DRY.
- If streaking occurs, too much product has been used. Use a wet towel to remove excess, IMMEDIATELY WIPE COMPLETELY DRY.
Note: this product does not air dry. Extra buffing with a dry cloth INCREASES bonding, repellency & longevity. Apply every 3-5 weeks for maximum UV protection. DO NOT use on unfinished leathers (such as suede), fabrics (canvas), floorings, clear plastics, gauge panels, or headlights.
