Well, it's been a while hasn't it? Back at another school vacation though, so able to continue working on my kit!
In my opinion, I've made good progress on the sanding. The pics below of me wearing it are kind of bad because I propped my phone up in the freezer and had it on a timer for three seconds, but this is where it's at now:

A lot of spots on the helmet I went over with spot putty and sanded down smooth, but some of those areas aren't sanded down after the last round of spot-filling I did yesterday (basically the right side of the not dome). I did hit a spot of trouble with my bondo cracking in some spots where the posterboard remains a little too flixible, so I went and finally bought some sintra today to create some reinforcement pieces to put on the inside. I'll be putting those in tomorrow before I finish sanding (don't want to worsen the cracking by sanding while its still flexible).
The dome, though quite smooth to the touch, seems to have some bumps in places, so I'll have to sand down those so that it's a nice curve.
i was also advised to use paintable caulk to go over some of the cracking because it's flexible - and to smooth it out with water since it can't be sanded. I'll be checking the stuff I have to see if that's a possibility without making another hardware store run (went and got some more spot putty yesterday, as well as some primer).
Once I've done all that, hopefully I'll have some better quality photos to post.
Also, now that I actually have sintra, I might be able to actually have an armor WIP thread sometime soon
Edit July 14 2018:
Added some sintra to the inside for stability:
Tested strength a bit, and it is substatially less flexy. Still am trying not to be too rough with it while sanding now
- good news is that it's no longer cracking every time i push the back even a little bit, which is what it was doing before. Used pieces of 3mm sintra. I was going to layer them, but I'm not too sure if my head will fit if I do. If I have more problems though, I'll probably try it and see what happens. Finished sanding to what I believe to be smooth today.
Plan to put on a coat of primer to see where the problem areas are, then back to sanding it'll be!
Edit July 15 2018:
(Badly) did a coat of black, which is my base color. Does bring to light lots of details that need working on, though, so that's a plus! Surprisingly, the cracks do not look nearly as bad with the paint on. Strange. I'll probably do some sanding and spot putty tomorrow, and maybe some epoxy on the cracks. It looks a bit rough as of now, but I feel confident that if I keep being patient it'll work (wasn't sure earlier this week with all the issues I was having with cracks) and turn out well. Luckily I have the rest of my kit to work on while waiting for putty and primer to set instead of literally watching paint dry.
All ready to get painting
Here are some pictures of the helmet in black. I missed the bottom edge of the raised part in the back, so taking note of that for tomorrow - I'll stand it up on a box so I can get a better angle to spray there.
