Derek,
We had a hose blow on our spray rig while spraying Specticle. Although the area did not completely die within a few weeks, it was injured enough that we went ahead and sodded it. We stripped the dead turf, mixed 2.5 gallons of liquid charcoal in about 200 gallons of water, and liberally watered the area with the mix. We waited a day, then sodded. No issues.
I would think that applying via a sprayer may not provide enough charcoal concentration to the depth you would need for the seed, unless you were applying at a high volume to penetrate into the soil. Simply spraying, then watering may dilute the mix too much and cause it to move past your seedbed. If you have the ability to gun it out - apply like watering the turf - then it should work. Aerifying would probably help, too.
