Anyone heard of the vinyl dressing called "303"? Also good for convertible tops??

Now that I have the white interior (ANOTHER car with white interior! Ah GOTSA be an automotive masochist!) and convertible top of Skyler the Drop Top Airvair clean enough for me; I am looking for some product to preserve and protect.

On another website the members were all touting a non-silicone, marine product called "303".

Anyone heard or it or used it?

I'm also considering "freshening up" the rear seat quarter panels with some white spray dye.

Any recommendations of which brand to use and tips/advice for usage?

(It's 32 degrees out dere as I peck this out, doing some "armchair planning" today.)

I have been using 303 protectant for years on my kayaks. No experience on vinyl tops, but if their marketing says it works on it, I wouldn't hesitate using it. What makes it worthwhile for me is that it is the best UV inhibitor I've found.

I use 303 on my inflatable boat and lots of other things. It is recommended by lots of manufacturers. Its good stuff. As for vinyl paint I have used SEM and its good stuff, follow direction.

I use 303 myself for both the interior vinyl and convertible top vinyl of my 65 monza. It does a great job of making the material soft and newer looking. I also use it on all the rubber door and window seals and it makes them softer. I used a convertible top cleaner first when I first got the car then I wanted something to keep it nice and to provide UV protection and came across 303. I put it on my top twice a year. One note though, after you put it on don't put a car cover over it right away. Let it sit for a couple of days before throwing a cover or blanket over it. I put my blanket cover over it once right away then when I took it off later there was some streaking of sorts I think because the blanket absorbed some of the 303 in spots. I just resprayed and rubbed it in no big deal.

I like 303 for the vinyl.

I use Ragg Topp cleaner and protectant for my convertible top and I like the non-shiny finish it gives. It also seems to bring the black back a little after it is treated. Been using it for about 4 years with good results.

I use 303 on my tires and never get any sidewall cracking. Good stuff to block UV.

I have used it on my Avalanche cladding. It looks okay, but doesn't last too long. Note, this is plastic, not rubber.

Several of the Chrysler/Plymouth Prowler owners I know SWEAR by this product and use it on their convertible tops (which are not inexpensive to replace).

I have a couple of sample bottles of the stuff that I was planning on using on my Prowler top but have not gotten around to it just yet. Yes I am a Procrastinator.

Whatever you do, Do NOT use an alcohol based "Protectant" like Armor All on a Convertible Top. It WILL do more harm than good. I learned through someone else's mistake when they used it on their convertible top. It looked great right up until it didn't.

I have offered to put 303 on the contact faces of my competitors race tires at the Autocross track. I told them that the tires would last longer on track. At least it would seem longer. They said no.

Didn't I see the car guys cleaning the painted surfaces of cars with 303, at the most Mecum auction ?

303 is the bomb! Been using it for years for all soft parts, boat parts, hot tub cover, even my fiberglass "wood" look exterior doors on my home. The only thing it didn't work well on was the hard plastic trim on my Silverado... mirrors, step bumper, etc. Seth also mentioned this about his Avalanche in a previous post.
303 is the real deal!
