  1. phil doncaster

    Five StarsVery Satisfied.

  2. Daniel Jordan

    Great ProductI`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.

    Good protection303 has been around a while and been known to be some pretty good protectants. I tend to use this on unpainted plastics and bumpers and it generally works really well.

  4. David de Groot

    Lives up to its reputationAfter recently purchasing a used car I did extensive research to find a product that would not leach the oils out of the plastic parts of the interior and also would leave a matte finish unlike armor all products, which generally have a heavy gloss.There are some cheaper products out there that actually will accelerate the deterioration of your dashboard etc. as the oil is of lower quality than the original factory oil in the plasticThis product delivered in all categories and I would not hesitate to purchase it again

    Been using for years!Great product, makes plastic trim look new. Lasts for 30-60 days on a 2013 truck. Bought some for a friend after he saw how good my F150 looked.

  6. Raymond Bierschenk

    Good productUsed this product on a kayak as sun protection. I’m sure it works but also makes the kayak very slippery which makes car topping interesting. Probably won’t use it on the kayak for that reason.


    Great product for protection of your inflatableLove this! Easy to use product, spray it on, wipe it off. It cleans and protects similar to like a wax. Makes cleanup of our inflatable after each use. Just as rinse down or spray off with water. Really like it and feel it protects the PVC materials

    Apply this to your rolled up awning!That part of your RV awning that is constantly exposed to the sun when it is rolled up is the first to degrade over time through exposure to the sun. I use this product twice a year and apply it to my rolled up awning and to all the plastic and vinyl surfaces on the outside of my RV. Like putting sunscreen on your skin, it does a great job of protecting your RV.

    Best protectant!Been using this stuff for years. I Use it on Jeep soft top, truck tonneau cover, auto interior plastics, etc. I also use it on air compressor hoses, garden hoses, and extension cords to protect them from exposure to the elements. If it’s plastic or rubber, especially if exposed to outdoor elements, they’ll benefit from application of this product. Leaves a nice even satin appearance, as opposed to a “fake” gloss. Use it sparingly and recoat if necessary. I saturate as small as possible (to avoid waste of product) piece of cotton rag to apply. Also, it contains no silicone.

    This is my new go-to for cars & boatsI bought this for vehicles that have a mix of leather and plastic interiors. Typically, leather conditioner leaves a residue on non-porus plastic surfaces and plastic products are not suitable for leather. This works great on both.I still used a leather conditioner on things when I can (leather seats, steering wheel) but in parts where there its a little more difficult to clean leather next to plastic, this stuff does great on both surfaces. And it lasts. I applied this months ago to the interiors of two cars and its still going strong. It leaves a dull satin sheen – not obnoxious like ArmorAll but definitely enough to let you know that its there. I really like it.I would not use it on a steering wheel, would use it very sparingly on the sitting area of seats if I had to as it does make surfaces a little slippery. Otherwise its great for everything (not fabrics, clear plastics, or glass, of course). Smell is not great like new car but not offensive, its pretty easy to work with, and it didn’t irritate my throat or eyes at all while applying it.
