The absolute BEST I have found yet that works amazing on my black car is Blackfire Wet Diamond Polymer Sealant spray. Leaves a killer shine with NO streaks. Easy on/easy off. I NEVER have to work at trying to eliminate streaks or a haze with this stuff. The shine is like a hard thick transparent glass shell. Amazing.
Middle of the road is Chemical Guys V7. Leaves a nice shine but can streak a little bit. Takes some mild action to get rid of the streaks and haze.
The absolute worst is Optimum Spray Wax. Despite the positive reviews out there this product totally sucks on a black finish. It streaks like crazy and leaves a haze no matter what I do. You have to work your ass off with a dry microfiber just to try and get the streaks and haze out. This is with a cool car, in a cool garage and low humidity. I've tried a spritz of water or a spritz of more product to get rid of the streaks and haze but it takes forever. I thought Optimum were supposed to be quality products? NEVER again will I buy this stuff for a black car. Never. I hate to throw the new bottle away so I'm currently using it on my white Challenger. It's a daily driver and needs the daily protection of a Carnuba based product. You can't see any streaking on the white so I can live with it.
