We applied DustLess to our community road (leads to 14 houses) two and a half years ago, and I know you suggested reapplying a small amount every 12 months to keep it like new, but honestly, it is still holding up like new. Sure dust gets kicked up by the tires, but you never see any in the air, because in a second it’s right back down on the ground, where it belongs. Really amazing stuff.
