This product appears to be doing what it claim.
I use it on the roof of the M/H and find that a yearly
application gives me the protection I want.
I do not have oxidation and discoloring on the roof.
I check the roof twice per year for sealing and use Dicor.

I use it on tires and vinyl and slide gaskets and dash boards, rubber seals, etc. Have not tried it on painted surfaces, however. Really like the UV protection!


PS. It is cheaper by the gallon.

I also use it on my roof. (and tires). My coach is only 2 1/2 years old so I can't speak for its long term capabilities but for now I don't have any streaking down the sides.

Used it at least once a year on the vents and skylights on the '02 Dutch Star. After 13 years the skylight still looked pretty good. I had replaced the vent domes with new double pane ones just because I got them free. Still have the old ones just in case. Yes, it does seem to work as advertised.

Used it for 10 years on my vinyl spa cover for UV protection (and on the Coach).

The color remained good but the cover hinge points failed after 5 years in Sacramento Sun.

I use it on tires, gelcoat roof (per Country Coach recommendation), and plastic and vinyl parts on the cars.

303 Protectant is water-based and therefore needs to be reapplied frequently in wet environments. Using it once a year is futile in most instances. Otherwise, it works very well.

I use it on my tires. The biggest disadvantage of 303 is it's staying power. Here's a quote from the company:

I bought the sample pack a few years ago. Didn't buy any more.
