I'd say more shine then I thought but not like Armor All.
Very happy with what I see so far

I have used Armor All and 303, both left a bit too much shine. But I changed my technique. I use the vinyl product of choice on the top and then I wash the car. The car wash soap and water removes a bit of the shine. Afterward it leaves a nice appearance.

Years ago I bought some POR-GLO from the same company as POR15. No idea what's in it, but it leaves the perfect semi gloss shine that dries fully and does not attract dust. It smells like mineral spirits when you apply and looks way too glossy, but when that flashes off it looks perfect. I only have to put it on every few years.

Not sure if you can buy any longer.

Edit: I did find on one site. http://www.allcarparts.us/catalogb.php?A=1&B=1&S=11&C=9
Almost tempted to buy a spare can. Goes a long way.

Some interesting, varied answers here.

I've used a spray on from Jax Wax that works well, also the 303 products are nice. I would avoid using Armor All on the top, I have seen that stuff destroy vinyl tops.

I'm so confused now ?????

I have the original vinyl top on my red Charger. In the 27 years I have owned it I have applied Armour All, 303, Meguire's or whatever other vinyl cleaner I had in the supplies cabinet in the garage & it still looks great. I don't know what is right or wrong they all work.

My 68 still has the original top and still holds a shine. I also used the paste stuff from the 70s. Last time I applied it was 1985. You would rub it in, let it haze, then buff it with a brush to remove any residue from the low spots. Finally you would polish with a rag. I really think it was very close to a shoe polish!!!
