The rear seats are filled and waiting for the putty to dry up. That's when I'll hit the sandpaper and
take away all of the excess putty and make some structure on the bottom of the "seats".
I also made a photo of the bottom side of the chassy so that you could see what I was writing about in
the previous post.

The twisted yellow things are masking tapes wrapped around the chassy so the putty wouldn't stay
on the chassy (where the rear swingarms are mounted).
