I'm not so concerned about filling imperfections, but am concerned about wrinkling and cracking over time. I'm not doing a superhero armor build, I'm working on dragon armor, which will look more organic, so imperfections are actually welcome and fine.
From your comments, I think I'll stick with plastidip. I won't need the flexibility for much of the build, but we all know that anything is going to take a beating getting worn. and I'd like this looking good as long as possible, since I'll be hanging around with friends with leather armor, and that stuff lasts forever.
BTW, in case anyone is interested, I also just purchased an interesting effect thing form my dragon's nostrils.. its a pretty clever assembly of a momentary switch, a minipump, the business part of an e cig. You fill it with a 50/50 mix of glycerine and fog juice, and you have a safe way to add steam effects to costumes! It runs off a 8 aa battery pack, and includes a super strobe to light the smoke at night. 9The same guy is doing the Ghostbusters proton pack overheating venting kit, and he converted his parts to accommodate my build. One fill should last for 100+ shots, and they can last 10 seconds long or more.
Here's his youtube video he posted for me showing the assembly working before purchase:

They guy's communication was excellent, and he shipped it the day after I confirmed everything was right and ordered it. Not sure if he is on RPF, but hes Jimfin on GBfans.
