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.

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

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.

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.

Rejuvenate your car dash
Is amazing on vinyl dashes, just be super careful to spray a rag or sponge and spread or make sure to protect your glass near by / wipe up immediately. I got overspray on my window and nothing i could find would remove the coating. I would call that a win for what it is however at night caused glare. Brings back the great look wish i started sooner

Good product
So sad that this is no longer sold through Canadian Tire, and thus I have to buy it here. Good product that does what it claims to do.

Perfect for our Spa cover
Needed a product to restore and protect our spa cover from the blistering Queensland sun. The original spa protect products just weren't lasting. So far this product is working far better and seems to be lasting longer, and has even restored some areas that were cracked and faded. It does make the cover a little slippery, but gives it a nice shine. We will see how it looks on another month of sun and weather.

Great non-slip product
Great product! I bought it for the side steps of my 4wd. It's not slippery at all and rejuvenates the black well. Clean the area well beforehand and let it dry. Polish in properly.

非常に守備範囲の広い製品です。
非常に守備範囲の広い製品です。 (1)ダッシュボードでの使用 1回目は良く分かりませんでしたが、2回目以降は、 しっとりとした艶が出ました。耐久性も良いです。 他のダッシュボード専用のものより良いです。 (2)本革シートでの使用 シートの汚れを除去した後で、本剤を塗ります。 程よい艶がでます。但し、滑りが良くなりますので 注意が必要です。 (3)タイヤ側面での使用 程よい艶がでます。汚れが付着しても簡単に落とせる ようになりました。撥水性もあります。 (4)エンジンルームやドアのゴムパッキンでの使用 耐久性を期待して使用しています。白化したゴムが 黒く蘇ります。 (5)ライトの透明樹脂パネルでの使用 紫外線による黄ばみ防止のために使用しています。 1年使用していますが、今のところ問題なしです。 (6)アルミエンジンブロックでの使用 汚れ付着防止のために使用しています。 非常に良い感じです。 (7)サンルーフでの使用 サンルーフのゴムパッキンの劣化防止、紫外線の車内侵入 防止で使用しています。特に問題なし。 (8)家の直射日光があたる部分での使用 ドア付近のフローリングやスチール製の玄関ドア などに使用しています。フローリングが非常に滑り易く なりますので、要注意です。階段での使用は厳禁。
