303 makes several different products and I use their fabric protectant on my top.

It's a great product, and every car enthusiast's garage should have some. If it's NOT painted, or glass, or fabric/carpet......you can just about 303 everything else on your car (rubber, plastic, vinyl, and leather [I like Zaino Z10 better for leather]).

I put ceramic coating on mine when I coated the exterior. Worked great.

Nextzett Plastic Deep. Great stuff.

I recently cleaned mine with Chemical Guys TIRE SHINE as I did my front cowl panel. It's meant to be used on a variety of materials and it worked well without feeling 'greasy' to the touch once it flashed off.

Mother's Back to Black ($7) covers rubber, plastic and many other materials. Inside and outside 911s or any other car.
Easy to apply and extra can be cleaned up. . ...good on worn materials, it last too

I've had good experience with Ultimate Black by Meguiars. It comes in both spray and gel form. Spray is great for mesh or grills where it's intricate and hard to cover with gel. Gel is more accurate, less overage. However, it is a somewhat artificial black. You can tell its been treated.

The advantages a) not sticky or slimy after it dries b) appears to last and last. As an experiment, I sprayed my dull black flood lights in my landscaping and they've been deep rich black all summer despite the water sprinklers hitting them every single day. The stuff is freakish. It's like there'll be Zombie Apocalypse and years later my flood lights will still be shiny black...
