Masking off, front wheels reassembled (these are a #$%^& to remove and reattach properly) Advice to anyone that wants to repaint their Tumbler: just mask the front wheels completely to make your life easier.
Front fenders reattached. These are only slightly simpler than putting the tandem steering assembly back together. It would've been a straightforward re-screwing if the wheels in the way didn't make it extra difficult to reach the screws and get torque.
Full body shot and a helpful model painting book that's full of tips for novices like me. Rear wheels (with repainted black rims) re-attached.

Things I still need to do:
1. Brush touch-up the sand paint in areas where my poor masking allowed the brown to bleed under the tape.
2. Touch-up some of the brown errors.
3. Paint the step pads black.
4. Fabricate the caged light bar and the long antenna that were only on the camo prototype.
5. Attach the rest of the braking flaps.
6. Mask the wheels and spray at least 2 dull clear coats over the whole thing.
7. Remove all the masking from the wheels, windows.
I think that's it.
