subpanel bonding???

good morning, I'm installing a subpanel today, problem is this, my main panel is the type with shared neutral/ground bar. should i bond the subpanel once installed? my guess is yes but thats why i'm asking the professionals because i want to do it right.

Bond the subpanel to ground, but not to neutral. Need a 4 conductor feeder for sub, 2 hot, 1 neutral and ground. Neutral and ground are seperated in the sub, neutral is isolated, and ground is bonded to can.

The neutral and ground are connected only in the main panel. You run a four-wire feeder to the subpanel (black,red,white,bare). At the subpanel the neutral and ground bars are isolated. This may require you to purchase an add-on ground bar kit for the subpanel and to remove the bonding screw and jumper from the neutral bus. The ground bar is connected to the subpanel box with machine screws; the neutral bus should be isolated from the box with plastic spacers or mounts (provided with panel).
