rejuvenators
Asphalt rejuvenators are only applied by contractors who are certified and trained by the manufacturer.
They are applied at a very precise rate, less than 1 gal per sq yard, this requires special equipment. Being solvent based, over application can actually dissolve the asphalt binder.

What you purchased at H/D was probably premixed coal tar emulsion. Three years is a reasonable life span.
One additional point, most Rejuvenators can NOT be applied over coal tar emulsion sealers. The solvents in rejuvenators will soften the coal tar into a sticky, black gooey mess that can take days or weeks to dry.
Speaking of mishaps. We had just finished sealing a large section of a shopping mall lot. A young punk on a motorcycle blows through the barricades onto the wet sealer. Needless to say, immediate loss of traction.
The punk, the bike, and oh yea his well endowed girlfriend ( tight shorts and even tighter t shirt) go sliding and rolling through the wet sealer.
The sealer is water soluble until it drys. Sooo.. whats a gentleman to do but offer to wash the sealer off with the water hose we just happen to have on the truck. Unfortunately (for them) this is a high pressure unit that we use to wash down the the pavement.
The punk was the first target, took a lot of diligent spraying to get the sealer off.
We were more gentle with the girlfriend. Poor young girl standing there soaked to the skin being leered at by six guys. The best part was when she took her helmet and cold cocked her boyfriend for being such a dumb ass.
