In the picture, the joint on the right, at the top, is not quite right. With the Dzus's buttoned up (they can change the profile) use a ruler or metal strip to see whether the front of the joint is low or the rear is high. If the front needs built up, if not with cloth, I would use Kitty Hair or similar, fiber re-inforced filler, instead of just filler. If the rear needs to come down to get it to match, you may need to add material to the underside to maintain body thickness and strength. Do your sanding with all Dzus's in place so the profiles are right. You will scuff some Dzus's but if they are all the same length, you can transfer the scuffed ones to where you are working at the time so you don't scuff too many.
Good luck

Tough crowd!
My friend photographer Simon davidson told me a young guy was looking at our tank at the lake one year ....
" is this a real one?"....
"Yeah" said Simon, "Of course it's a real one"
"Like from back in the day? How old is it?"
"Well, I think it's less than ten years old"
"Huh?" said the kid, who obviously thought it was from the fifties or something
"How come it looks so f#%$^$&"...
It's not just "the first run down the track" for us, there's the hundred miles of terrible road into the lake, it's beats the hail out of everything...
yours is looking good btw.
