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.
