update on my helmet. it has been primed 3-4x with some slight filling and here and there more than the filling that I did. My shoulders needed some light smoothing out to make it look better. Also, while adding multiple layers of primer, we noticed that the outer seams between the two halves had a flaw where the lines on the side of the helmet weren't as smooth of a transition as they could've been. We also noticed some flexing in the ABS helmet at the seem in the center.
Since the painter of the helmet is a friend of mine, I trust him doing some custom body work as needed. He's been in the professional auto body / custom audio field for years and he is great at repairs and customizing.
We ended up cutting out a small section of the sides of the helmet in order to fix the problem. It was re-filled and sealed with a new auto body filler that he uses and says is 100% better than anything you can find in a retail store. This setback has added 2-3 days to the final paint job but I don't mind because I want it to look as perfect as can be
Here are some pictures of the work done...
