Zouave146 I take your points, both valid. On the weathering, I did consider the age of the vehicle but in the end the urge to weather got the better of me!!
Anyway if I hadn't weathered, someone would have said that it needed more weathering!!LOL.
Zokissima the water is artist's acrylic medium. I tested a small area before I did this dio and it dried quite clear. Unfortunately on a larger area it does look a bit milky.
Thanks again
