Also got my paints in and started working on the helmet seam. Still needs some touch up and a little more clean up work but I’m pretty happy with it. I followed
TheSwede ’s process for filling the gap.

you mentioned fiberglassing the helmet, right? That might be a very very good idea expecially with the efx for a couple of reasons.
Disclaimer: I've never held an efx before so my thoughts are based on experience with other "plastic" helmets.
Plastic helmets tend to be more flexible then full fiberglass buckets. In my estimate that flexibility is a bonus when it comes to physical shock damage, like dropping a helmet. It would maybe get damaged but not shatter into pieces.
With that flexibility comes the issue of gaps. Not only their mere existence but that they will flex; widen and shrink if you handle the helmet. Normally not a problem, but you will be filling the gaps in. The flex in the helmet and the widening and closing of gaps may lead to your filler and paint cracking in those places.
Thats why I think fiberglassing the inside is a really good idea as this will add rigidity to the helmet and prevent the filled gaps from flexing and the filler and paint from cracking.
(At least that's what I think).
Moreover (this is speculation though) even in case of dropping a helmet, the fiberglass might probably help. Adding fiberglass will give you two kinds of "strengths" in the helmet: the flexibility of the plastic and the rigidity of the fiberglass. This could lead to the fiberglass preventing the helmet from flexing too much when being dropped, thus preventing the plastic from damage due to overstress.
In other words, the fiberglass may help to absorb some of the initial blow, likely shattering it in the process, but preventing the plastic from overstressing itself.
As I said, this latter part is nothing but a theory and it might not help at all, maybe even hurt due to the helmet becoming heavier and thus the impact force being greater. So read it with a grain of salt.
For the gap-flex-issue, I'd say its a very good idea!
