I sanded smooth a lot of the bondo the other night. Here's some pics to show the end results. I'm much happier with the finish of the helmet now. I'll still work on a few minor trouble spots here and there, but I think this one is getting close to being ready for primer.
I also got quite a bit of work done on the Clone Pilot Helmet, but haven't had the chance to shoot any pics lately. My phone was on the charger the day I did all the work. I'll post up some pics of that progress this weekend.
