It may be resin encapsulation(Potted). It will protect the circuit from environment and act as a good heat conductor also.

Photo would be good.

A resin sets to a hard compound, there are silicone potting compounds but these are still quite hard

The green thing is solder mask, so you cannot solder on other areas except the pads.

The Green layer is called as soldermask layer, it gives permanent protection to copper traces.

I guess he is not talking about solder mask but i think as you said a gel like substance sounds more of a glue to provide extra holding and firmness to components.
still do attach Pics they are obviously more helpful in understanding the query.
