I finally bought the Wurth at Autogeek.net there are a number of other places that carry it as well right now.
What I found interesting is I stopped in probably 6 or 7 Pepboy, Auto zones and Advance Auto Parts who all claim to carry Dupli-color and every single one of them was sold out of Wheel Silver and could not tell me when it would be coming in. I called a few others and same story. Well Dupli-color website claims Wal-mart carries their paint, I think someone forgot to tell them Wal-mart now only carries Rust-oleum paints.
I ordered form autogeek last week and still have not gotten confirmation it was shipped, I think I need to call them and see what gives.
BTW, rust-oleum wheel silver is not a match it has too much and too large metal flack in it.
