I will be getting a black car and I was told to use Liquid Glass, but I have heard a lot about Zaino. So what wax/polish should I use?

 

I've seen results of Zaino and it's good. Never done it myself. Haven't set aside enough time for all the steps.

I have used Zymol though on a black 68 Camaro that was cleared about 3 years ago. I never wash the car. It doesn't get daily use, but when it does get dusty, I Quick Detail it and they apply Zymol.

I like it because it makes the black blacker. You can see it as you go across the panel getting deeper, darker and wetter. The key is to go in straight lines for application and removal. But at 90 deg to each other. So, if you wipe left to right to apply, go up and down to remove. It's a one step product, so that makes it nice. Another key is to not let it dry on the panel and to do small sections at a time.

Here's my car.

 

Thanks I will also look into that product. By the way your car looks great.
