    303 UV protectant

    The stuff might be indeed providing a decent protection and I have been using it on the vinyl top for three years. Nevertheless, the ease with which it dissolves in water makes me wonder how much remains on the top after a 10 minute rain... 1%? 5%... Could be just a feel-good thing and waste of money ( a $16 bottle is only good for a few applications) for those of us whose cars are parked outside year around.

    I use it and love!!! My machine does sit in the garage unless its nice outside so I don't worry too much about it washing off. There is a little bit of "feel good" after I apply it, much like everything else I do for my car!!

    I also have been using it for over a year. It looks like it works.. After I had a new top on my 95 FB the guy gave me a bottle of 303 and said "put this on once a month and it will stay looking like new" ... So I have been and after it does still look new...Been using it on the new top on my 81 Deville. Looks good...

    I have used 303 for many years I first bought it in the USA on a trip, best vinyl conditioner I can find here in Canada. I have recommended it to many people but once I tell them it's a little more expensive, they usually say armorall is just as good. Oh well you get what you pay for.

    Armor-all is nothing like 303. They should do some research before they put that on their top/vinyl.

    I've tried 303, but had the same problem with it running in the rain (and it makes the top look dry as hell), so I don't use it. The sun over Ohio isn't that brutal, so it isn't much of a testament, but without any regular treatment, my vinyl top is in the same condition it was when I got the car six years ago.

    Basically the best things you can do is keep the top clean and out of the sun (park under the tree on your neighbor's lawn). I use Murphys Oil Soap to get all of the dust off and give the vinyl a nice wet shine; it may provide some kind of protection as well, but I don't know.

    Sven, is there a different consistency of murphys oil soap for cleaning and giving a wet shine (or does it do both things at once)? My top is always dirty (dusty) and looks like crap (well it looks dusty) except when its wet.

    i also use murphy's oil soap on my top. I just pour it directly on the top and use paper towels or a washing towel to scrub it in good.

    Love the look it gives the top. so clean and shiny

    Re: 303 UV protectant

    303 works great. I apply 303 a couple times a year and the vinyl top on my car, and the interior plastic, still looks like new after 7 years of the car living outside for 2/3 of that time, and it holds up through days and days of hot Florida sunshine and tropical storms

    303 should not come off if it is applied per instructions which is to spray on, then wipe to a low luster shine for full coverage.

    If the vinyl on your car has previously degraded from exposure to the elements then 303 won't restore the original shiny layer your vinyl has already lost. At that point you need to constantly apply some other product to shine the vinyl to make up for what mother nature took away. If the vinyl on your car is shiny and like new then 303 will keep it nice.

    I have used 303 for years, since the early 1990's, on both cars and boats, and I feel nothing works better.

    No... I just pour a thin line across the center of the roof, and then wipe everything down with a damp rag. The oil soap removes the dust and leaves a shine.

    My top definitely saw some sunshine if not in Florida where the car spent most of its life then in NY. The vinyl is discolored and dry... I do not care much of the looks, just strive to make it last. I have been thinking of combination of 303 with following application of something not easily washable away with rain.
