Any chemicals than can be added to retail driveway sealer and patch to speed up drying and hardening.
My last batch of driveway sealer and patch is taking for ever to dry. Mostly because the manufacturers caved to the tree huggers took out the chemicals that helped dry and harden them(VOCs including some the lacquers). Patch is still soft after 48 hours in hot weather. Sealer 12 hours to dry on flat surface and 36 hours in small cracks. Never a problem until about 6 years ago. I'm on my third manufacturer and store in 6 years to no avail.
I was thinking of adding lacquer or acetone or even denatured alcohol. I tried mortar mix on juicy spots and sand on damp spots today. I see in morning the results.
