Black and Decker Valve refacer

[Seabees]

Howdy boys, I was just given one. WOO HOO! Already used it, but it needs to be taken apart and cleaned up pretty bad. And as Kurt in NJ says, I wouldn't stand in water when using it! I think I'll see if I can ground the plugs. Not a sparktrition, so I'll leave that up to a buddy of mine...... Have any of you torn it down completely and cleaned it up? I think that's what it will need. Thanks guys!
