Great Product
I`ve used many surface protectants over the years, all silicone based, and this stuff outperforms it by a mile.I have a roller shutter which covers the bed of my pickup. It has a vinyl finish that is relatively vulnerable to winds and weathers but an occasional wipe over with the 303 and nothing can stick to it.

Great product
This helps to prolong the life of many items we have which are subject to constant attack from the sun.

Ideal for rolling Tonneau covers/rubber and silicone seals
Good quality protectant for my Tonneau cover on covering my open-bed on my ranger. I just cleaned with power washer and moderately dried the cover before applying using a thin relatively absorbent cloth to wipe/buffer the protectant after lightly spraying the cover a section at a time. One week later a shine is still present and no issues with either build-up or sticky mechanisms. Easy to apply. Instructions state to use sparingly which is a good thing as the protectant is a little expensive but you receive nearly 1 litre so the bottle will last a while for the average user unless you have a large inflatable/boat to protect. I have also used on plastic/rubber seals by applying to a cloth first and then applying to insure the solution is applied correctly and not on glass.

Arrived quickly and seems to work well on hot tub cover with heavy weather exposure. Time will tell

Simply the best...
Yep, that's a shocking cliche, but when it comes to dressing the plastics found in car interiors & engine bays, this is the best product I've ever used. If you've not tried it before, get it on.

Best Marine protectant

303 Protectant is the best treatment for gaskets, tires and untreated matt black plastics when detailing cars and trucks. It doesn’t turn the tires brown after UV exposure, keeps the gaskets soft and pliable plus enriches the look of the matt black, unpainted molding/trim. Also it can be used sparingly. A 32 oz spray bottle goes a long way when used on a pad or small soft microfiber towel. I think it’s a great product!
