Q: I dont see it in the picture and there is no description. Does this gun include the chemical container or is it sold separately? Second, does this gun have a dillution setting knob?
A: Hi Gonzalo,
This item contains an empty bottle so that you can fill it with Viper Coil Cleaners. It does not contain any Viper Coil Cleaner solution, it only includes the spray gun fitting and the empty bottle for Viper Coil Cleaners.
This item also has a dilution setting for easy use.
