I've used another brand from Menards that seems to fill in shiny black and quite hard.
The Black Jack from Lowes is easier to put down after proper mixing.

I have a small footage yet to do (likely Wednesday) and will observe the result as cooler weather comes on.

The surface of my blacktop was starting to degrade, the cracks were larger, the concrete underneath was chalky.

I spent 4 days chiseling out the broken up parts and patching it all up with blacktop. (Something called aquaphalt, expensive. You spray it with water to activate and tamp it down. Cures within 24 hours which is a major consideration.
Glad its done.

I also used Black Jack sealer. Done before winter and hopefully it will hold for the next 4 years. After that its time to replace the whole driveway!
