Neil Barrett netted on 29 minutes with a 20-yard strike which gave Grays keeper Ross Flitney no chance, before Long fired home just before half-time.

Grays pulled one back just after the hour mark as defender Alan Power scored with a 12-yard drive.

But Long set up Michael Bostwick to score from 12 yards before driving in late on to complete the rout.
