Very good, Tony! But it's not nearly finished....
Now, throw a ligt wash of raw umber oils on it--you don't want t priistine white like some bride on her wedding day.
Then, try a little more drybrushing with the base color. You want to throw your entire arsenal of effects at it. Highlight all those protrusions with a little gray.
Get a sewing needle or similar type implement and add some fine scratches. Those scratches will also help you get under the paint more to the hairspray, so give it yet another shot at rubbing some smaller patches off.
Even try some sandpaper and give it a scrap or two across the tops of those storgae bins on the back, just for kicks. Like I said--throw everything you can at it.
Judging from the amount of erosion you got, I think that you might have gone a bit heavy on the whitewash coat. It looks pretty opaque to me. Also, I just don't think that you've given it enough of a rubdown yet. Try to attack those fenders more--like I said, some fine scratches will help yuo get under the white--or, it's possible that just some careful drybrushing willl throw all those high spots into relief and make the effect all just come together.
Good man--you're showing your cajones! 
lol!
