A few guys use it, but I don't think it is a great match for Wizard green. I think it more closely matches the 1940s and 50's Elgins. One of the guys here recently painted a WG4 with what I thought was a really good match. Scroll back through the posts and you should be able to find it.
If you want to buy the exact match, Peter McDowell sells it at www.nymarine.ca.
