I really like following this thread, learning a lot - just wish I could work in metal. I was surprised to see you using Cold Galvanizing as an undercoat as I wouldn't have thought it would work out okay with normal paint (no knowledge just seat of the pants thinking) but apparently it does - the only place I've ever used it is on the valley flashing on my house roof.
Larry I wish I could craft wood like you do. The cold gal works very well on ferrous metals.
