We have an optional bug sprayer available for the Softgloss to spray a presoak to the front bumper cover. It's a small manifold with 4 nozzles positioned about 2' in front of the front bumper cover. The retrokit is P/N 26828-000. For machines with an FX2N PLC, it requires PLC program 25696-000 rev O or higher, and the program is already compatible for any MAXX units with either FX3U or FX5U PLC's.
