Illustrator Scripting :: Change Stroke Color Of Object In A Script?

I need the finished script to create a rectangle with no fill and a 20% gray stroke to outline each artboard. I dug this up off these boards, which works perfectly except the rectangles created have no fill or stroke. certainly save me a lot of time drawing rectangles on a daily basis.
 
#target illustrator
var docRef = app.activeDocument;
var artboardRef = docRef.artboards;  
for(i=0;i<artboardRef.length;i++){     
var top=artboardRef[i].artboardRect[1] ;     
var left=artboardRef[i].artboardRect[0];     
var width=artboardRef[i].artboardRect[2]-artboardRef[i].artboardRect[0];      
var height=artboardRef[i].artboardRect[1]-artboardRef[i].artboardRect[3];      
var rect = docRef.pathItems.rectangle (top, left, width, height);     
rect.fillColor = rect.strokeColor = new NoColor();    
}
