As a kind of "life support" for a driveway near death, you get some extra
time. That money is better spent on fresh pavement.

A smooth dark black driveway makes your whole house worth more money,
and makes it easier to sell.

Cosmetics have some value. By all means, put on a fresh coat of paint on
your driveway, as on looks alone it may more than pay for itself in
perceived value in the eyes of a buying prospect. But in terms of genuine
useful life, not in my estimate.
