Finally got my helmet smooth enough so I could go about un-smoothing it. 
First I mapped out the wear pattern. This may be not perfectly screen-accurate but the way I'm doing it is the most worn parts will be nearly smooth, then a layer of texture spray, then the raised parts with stippled Bondo. I used my template to paint in mustard for masking the smooth parts.

After masking I sprayed everything with texture paint. Then I sketched out the raised areas and stippled with Bondo. After that cured I hit it with another coat of the texture and washed everything off in the sink, using an old toothbrush to get all the masking off. Finally I hit the smooth parts with a high pass from a standard grey just to get a tiny bit of texture.

I hit the helmet with the ol' one-two of Spring Grass and Italian Olive, then began masking the cheekbones. Sprayed flat black on those in an attempt to make dark green but I think I went a little far. Then masked off the red and hit everything with a few coats of clear. Now it's really looking like a proper Boba bucket! Still need to do washes and weathering but here's how it stands. I'm really happy with how the texturing turned out. I also added an MQ-1 circuit board I modeled to the back. So much work for something that's barely visible!
For the ear pieces I painted the right side with a gold and hit it with a matte clear. The left side is straight Italian Olive. The rf stalk is Rub N' Buff. I'll be hand-painting the details.

Up next are the vambraces. Was hoping to have this done for Halloween but I've gotta shift focus and get my son's Rebel pilot costume done!
