I looked on Amazon and there was a variety of different 303 products.
A quick Google brought up one of Zachary's videos:

Product Description
Originally engineered for aerospace and aviation applications, 303 Automotive Protectant provides superior UV protection for any rubber, vinyl, and plastic surfaces of your vehicle, such as your dashboard, windshield wiper blades, and even your tires. Unlike many protectants that leave greasy residues, 303 Automotive Protectant dries to a clear matte finish without that sticky, shiny slick feeling. 303 Automotive Protectant not only protects against fading, discoloration and cracking from harmful UV rays, but repels dust and stains, too. Simply spray on and wipe dry for a beautiful, matte finish. Best of all, each application will last up to 30-45 days. Great for use on a variety of surfaces such as: vinyl, plastics, synthetic and natural rubber, leather, PVC, gel coat and fiberglass. Ideal for use on your dashboard, other vinyl/leather interior surfaces of your car, tires, windshield wiper blades and more! Not for use on unfinished leathers (such as suede), fabrics (canvas), floorings, clear plastics, gauge panels, or headlights. Usage Directions Use only on clean surfaces. Out of direct sun, spray surface with 303 Automotive Protectant and
WIPE COMPLETELY DRY with a clean, dry microfiber towel. Can also be applied directly onto microfiber applicator or towel before using. 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 and longevity. Apply every 3-5 weeks for maximum UV protection. For the best results, we recommend following these easy steps: Step 1: Make sure surface is clean and dry before using. Step 2: Spray product directly onto surface, or spray onto microfiber to apply. Step 3: Wipe dry with a clean, dry microfiber towel. Use a wet towel to remove any excess. Step 4: Evaluate your results. Extra buffing may be required for optimal results. It is recommended to re-treat every 30-45 days.
