Got the Rhino nearly done tonight.  I took these pictures after removing the liquid mask and salt.  Tracks still haven't been added.

These were taken though before I thought "Gee, this'll look great when I add the rust detailing."  Long story short, no.  No it did not look great.  In fact, I kind of ruined it.  I've managed to salvage most of the tank, but the top hatch and side hatches are pretty well botched.  I'll probably respray them tomorrow.  I might be able to save one of them as-is, but not the other two.  Shame, because it actually did look quite good as it was.  I should've just left it alone.  Well, lesson learned.  On my next tank, I'm not going so crazy and I'm certainly not going to try and do the rust effects on it.
