Ziebart Undercoating?

[NeckBreaker]

There is a special for 139.00 for undercoating spray or the rust proofing. Should I do it or not. Anyone have this done. Will it look like shit or actually look nice having everything black underneath.

Wanted to do before I put the shocks traction bars and springs on. :shrug:
