Dear BF, I've heard a few

Dear BF,

I've heard a few options,
- thin hi-reflective trailer tape from auto stores
(could be too thick for HO, you decide
http://www.reflectivelyyours.com/generic123.html?gclid=CLSxoJ3KxpICFRr7lgodXDsbbA )
- Hi-vis yellow decals + "gloss coating"
- MicroScale was rumored to be working on reflective decals at one point
http://www.microscale.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=MC-4122&Category_Code=STRIPES&Product_Count=1
- Avery reflective tape
- silver decals (static car model stuff?) + yellow ink overcoat?

True "scale thickness" yellow reflective tape seems to be one of the "holy grail" items at this point for freight car weathering fans....
