303 Aerospace Products

Harbormaster Notes:
The first time I saw 303 Protectant was at a trade show in Atlantic City about twenty years ago. It bore an uncanny resemblance to skim milk. I was skeptical at that first viewing that a product from California could surpass its wildly popular competitor. Well, fast forward two decades to realize how very wrong a Harbormaster (that's me) can be.

303 Protectant is one of the most versatile marine and automotive products we have ever used. It is an Armorall style product, but the similarity stops there. It is WATER BASED and non greasy. It is truly a UV inhibitor and acts as sunscreen for car and boat interiors, dashboards, vinyl, tires and does an excellent job on leather too! It is unparalleled on thermoplastic canoes and kayaks. It will stop the chalkiness that occurs when a plastic boat is left outdoors and subjected to the sun's damaging rays. PERSONALLY I think this is the best product I have ever used for strataglass clear vinyl that is found on boat enclosures and sailboat dodgers. I have sold this to many friends and business associates and everyone raves about how great a job 303 Protectant does! Spray a little 303 Protectant on a rag and recondition you windshield wipers. They will last longer and perform better. With all the money you save on wiper blades you can add me to your C Try and keep if off your windshield though, as it makes a mess that can easily be cleaned with household window cleaner!

303 Convertible Kits: The most ignored part of a convertible is the rag-top itself. Most people do not know how to care for their convertible tops (myself included), so they do nothing. The most I ever did was to take a damp rag to remove bird poop. Naturally I was truly offended that a bird would have the gall to strafe my car! Using 303 annually will keep your vehicle's top as clean and waterproof as the day it rolled out of the showroom. Determine whether your top is a fabric or vinyl top. Most imported cars are using fabric these days. Domestic manufacturers are still using both materials depending on what model car you have. As a general rule, most vinyl tops have a smoother more satin like feel. Cloth tops are rougher in texture. To be absolutely sure which type of construction you have visit your local dealership and they will advise you.

303 High Tech Fabric Guard is the only product endorsed by SUNBRELLA to waterproof boat enclosures and bimini tops. It will rewaterproof nylon tents,waders,winter boots, patio furniture, patio umbrellas, RV and house awnings and many other fabrics.
