Which sealant will be better for my 6 year old faded concrete stamped drive?

TAO claims to do 40 square meters per gallon at 514 Baht/gallon.

Bosney, the green one, claims only 20 meters/gallon @ 460 baht per gallon.

Think possibly to get something in the middle, @ 30 square meters per gallon?

try NIPPON reasonably priced and for the price good quality

TOA = rolls royce quality but price to match they excel in wood stains /varnish etc but again top quality = big bucks
