    Aerospace Protectant 303®

    • Powerful UV blockers prevent fading, cracking and premature aging
    • Dries to a clear matte finish

    • Safe and effective for: vinyl, Plexiglas, carbon fiber, rubber, plastics and finished leather

    No other product provides this much protection for your boat and water gear. Use Aerospace Protectant to keep your boat’s seats, sails, hull and windows colorful and clean. Marine Aerospace Protectant is a premium protectant designed to safeguard boats and boat equipment against the damaging effects of daily exposure to UV rays. It’s safe for use on outdoor gear and apparel, too.

    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. Aerospace Marine will even help keep fishing gear clean and prevent inflatable boats from sticking together during storage. 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.

    No other protectant beautifies as intensely or preserves as powerfully. Keep your boat, water sport equipment and outdoor gear shiny season after season.

    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.

    Great for use on a variety of surfaces such as: vinyl, leather, plastics, synthetic & natural rubber, eisenglass, PVC, gel coat & fiberglass.

    Ideal for: Hypalon inflatable boats, wet/dry suits, tires, side-out seals, RV EDPM rubber roofing (for your safety, never walk on a wet roof), helmets, visors, and goggles. Not for use on unfinished leathers (such as suede), fabrics (canvas) or floorings.

    303 Aerospace Protectant Has Many Applications, Including:
    • Boat Interiors: Spray on your vinyl boat seats to prevent them from fading and cracking during boating season. Will also help keep them clean from dust, sand, and will help prevent those dreaded sunscreen stains
    • Boat Bimini Tops: Protect your boat cover all year from the sun’s harmful UV rays (which can cause fading/cracking) in the summer months, and in the winter, it will keep the material pliable and prevent it from drying out and cracking. 303 Aerospace Protectant will also help make snow and ice accumulation easier to remove/brush off as well.
    • Boat Fenders: Use on your boat fenders to protect from the sun’s harmful UV rays (which can cause fading/cracking) in the summer months.
    • Outdoor Furniture: Keep your plastic, metal, or wicker outdoor patio furniture from fading, cracking and chalking. It will also help repel dust, dirt and grime, that can quickly accumulate on your furniture during the enjoyable BBQ season

    Excellent product that performed as well as it suggested. Didn't buy for a boat but to clean up the rubber formed cymbals on an electric drum kit. Far exceeded my expectations. Also used it on the windshield wipers on our car. Brilliant result and now I don't need to buy new wipers just yet.

    A+++ Excellent

    The Covershop exceeds all expectations of customer service, communication and excellence of product. I was highly impressed with updates on delivery notifications. The product was very securely packaged as to avoid any damages (not only was product in a sealed bag to avoid possible leakage, it came bubble wrapped, card wrapped and most impressive it was sent in a recyclable postage bag) - well done Covershop. The product itself has also gone above and beyond any other "protective" sprays, giving the results of a very high quality protectant. I wouldn't purchase anything else now. Would definitely recommend this company and the purchase of their products.

    Great Service

    I thought the service was excellent, great communication about when the item was sent and updates and when it arrived it was well packaged in not a plastic bag but a plant based bag, 100% thumbs up for that really impressed. I would definitely use your company again also the item was better priced that others for the same product.


    Great for Cars too

    This stuff is seriously good,soak window wiper blades in this over night, never have to buy another set again. Soak engine belts timing belts,etc spray your suspension Bush's, door seals, engine hoses you name it! If it's rubber plasic etc it will keep it supple and like new if you keep applying it every 3 months.

    Seem alright

    Have applied the product and am so far happy and will buy again.Had brought an Akron inflatable and it went all sticky and they said it was due to Sunscreen.Of corse this is bullshit as the product is inferior and I will buy a boat of better Quality next time that is not PVC.This product is buying me time before replacement.
