Kenny As the others have said, you really must have dedicated equipment/feedlines spray guns etc.. for any silicone coating. You should also consider that there will be some cross contamination into/onto other working areas including the floor! We dedicate individual dip and spray coating machines for each coating type viz: AR - UR - SR You might ask him why silicone? Its also a major pain in the wazoo to repair and generally costs more. If its a MIL Spec application, AR and UR will probably do a better job.
