Ultimate Surface Protection. Trusted by Pros. Proven to Protect.
Originally engineered for the extreme conditions of aerospace and aviation, 303® Aerospace Protectant has become the go-to solution for protecting surfaces in homes, garages, marinas, and beyond. This powerful, water-based formula delivers long-lasting UV protection for a wide variety of surfaces—without leaving behind a greasy or shiny residue.
Unlike conventional protectants, 303® dries to a clear matte finish, restoring color and luster while helping prevent fading, cracking, and discoloration caused by the sun’s harsh rays. It also repels dust, dirt, and stains—keeping your surfaces cleaner for longer.
From boat seats and vehicle dashboards to spa covers, helmets, tires, and patio furniture, 303® Aerospace Protectant helps your favorite gear look newer, longer.

For clear vinyl windows and enclosures, use 303® Clear Vinyl Protective Cleaner for safe, streak-free cleaning and UV protection.
Usage Directions:
Use only on clean, dry surfaces. For best results, clean first with 303® Multi-Surface Cleaner.
Place a drop cloth underneath the surface to catch overspray.
Out of direct sunlight, spray 303® Aerospace Protectant directly onto the surface or onto a clean microfiber towel.
Wipe thoroughly and completely dry—this step is crucial for performance.
If streaking occurs, too much product was used. Remove excess with a damp towel and buff dry.
Note: This product does not air dry. Extra buffing improves bonding, repellency, and durability. Reapply every 3–5 weeks for continued protection.
Real-Life Applications:
Boat Interiors: Protect vinyl seats from cracking and sunscreen stains while keeping surfaces dust-free all season.
Automotive: Use on dashboards, door panels, tires, and trim for a rich, like-new finish without the greasy shine. Helps maintain convertible top flexibility and protects against UV exposure.
Spa Covers: Preserve your spa cover year-round. Prevent drying in winter and fading in summer. Bonus: helps snow and ice brush off easily.

303 Protectant is a water-based proprietary formula that contains no petroleum distillates, alcohol, mineral oil or harmful silicone oils.
303 Protectant does not contain any harmful silicone oils, which can dry out and damage surfaces.
Originally engineered for aerospace and aviation applications, 303® Aerospace Protectant is a premium surface treatment that instantly beautifies and provides superior protection against harmful UV rays that can cause loss of mechanical properties such as: discoloration, fading, embrittlement, cracking and/or chalking. Treated surfaces repel dirt, soiling, and staining.
303® Aerospace Protectant is great for use on a variety of surfaces including vinyl, plastic, synthetic and natural rubber, PVC, finished leather, colored gel-coat fiberglass, and more! DO NOT use on clear plastics, unfinished leathers (such as suede), fabrics, floorings, gauge panels, or headlights.
Each formula is unique and specially formulated for specific applications.
You may use 303® Aerospace Protectant on wicker furniture as long as it is smooth. It is not recommended on weave or porous surfaces as they may trap excess product which could later cause streaks.
No, we do not recommend using on fabrics since this is a water-based formula.
Yes, it can be used on Neoprene material. However, make sure to wipe off as much product as possible during application and make sure that it is completely dry before exposing the material to water.
Yes. You can certainly use 303 Protectant on poly-coated furniture. Just remember to fully wipe off the product!
It is recommended to re-apply product every 30-45 days for best results, and maximum protection against the sun’s harmful UV rays.
To remove the cloudiness on the glass, we recommend the following steps…
1.) Put hot water on cloudy surface, the hot water will strip the Aerospace Protectant off the surface. Be very careful when handling!
2.) You may have to agitate the surface. Use a soft brush or something that won’t hurt the surface.
3.) Wash off with soap and water.
On average a 16oz. bottle treats 40sq. feet.
Typically 303 Protectant will leave streaking if too much product has been applied and not fully buffed into the surface. 303 Protectant needs to be buffed/wiped so that it can bond to the surface. Sometimes, you may not be able to see excess product on the surface but streaking can occur later. We recommend washing the surface with hot water. Then once fully dried, apply the 303 Protectant again.
No. 303 Aerospace Protectant is a water based formula that contains no flammable materials such as petroleum distillates or alcohol.
There is no unified industry standard rating for UV protection such as in skin sunscreen (SPF or Sun Protection Factor). However, 303 Protectant will block up to 98% of UV radiation if used properly and consistently.
The label (marine, automotive, patio, etc.) varies depending on which market you find it in. The protectant formula is the same featuring the product benefits and mode of application. So whichever item (label) you get will be a great choice!
