No, Darren, he's not pulling your leg.  Check out
http://www.polysciences.com/tech_sheets/105.html.  Batson's Corrosion Kit
is the name of the product designed for demostrating vasculature.  I don't

curious, why would you need a stain to differentiate veins from arteries
when their histological appearance is so different?
