Had the "White58" project on hold for a long time. Looks like you beat me to the finish Oct
On the flip side, the panel line in both the model, and the profile pic too, seens to be a bit too strong.
The white coating is usually a water soluable paint hastily applied, and would peel off/fade away upon the surfaces that meet strong air friction most frequently(usually leading edges), showing the greenish under layer. Perhaps you could apply a bit of this effect too!
