I use a lot of products from the big brands and this for exterior vinyl and rubber is the best of all. It holds up well on vehicles and boats through the sun and rain.

The bottle had leaked in the box. I'm not sure who shipped it but the top was a little loose on one of the bottles. This 303 is the best stuff I have ever used on my boats. I had a 20 year old pontoon boat that I treated with 303 several times a year and the seats never cracked and looked almost new when I finally sold it. This is an amazing product.

I bought this product based on recommendations from various manufacturers on how it should be applied to their products to protect from UV as well as keeping vinyl and rubber supple. I use it on my rotomolded kayak, dry bags and many other items.After three years it seems to be working well. I’ll update this in a few years, as only time will tell.

Bought this to clean and protect my pontoon seats. Its a work in progress, and so far very satisfied with its result. The uv protection is a necessary and hopefully saves my seats lol

Purchased to use as protectant on my older pontoon boat’s upholstery. Easy to use and seems to be working as advertised. Smells good too!

Used to spray in artificial flowers and works well. They lasted all last year and very little fading. I am able to reuse them this year and they still look great.

Best protectant you can buy.Doesn’t sit on a surface just looking oily, seems to do a better job of not attracting dust when compared to armor all.Bit pricy, but it is what it is.

Best stuff in the World to protect your kayak and boat colors from fading. I have a $4,000 fishing kayak (Old Town 106MK). I wash it thoroughly and then dry it. I them apply the 303 marine protectant. It shines the kayak up and seals it. My kayak is 5 years old and she looks like NEW. This is the only stuff I would put in my prescious kayak. I highly recommend. 👍😎🎣🐟💦

This stuff worked amazing! I’ve done a great job with keeping my 2022 Wrangler soft top in great shape, protecting the windows from getting scratched and such, but had never applied any type of protectant so it was starting to look weathered/dry in spots. After a couple of applications it looks new! Highway recommend, only start using it sooner than 3.5 years in!!

A little pricey, but great on vinyl in sunny locations.

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

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.
