UPDATE 6-21-12
OK, the helmet needs to be restarted, AGAIN, ARGH!!!!!
BUT, I have found it to be a learning experience in regards to using drywall mud in place of bondo. I used resin for the outside, then Rondo (Resin/Bondo) mixture for the interior, which I think may have contributed to the warping, UGH. I should have kept a better eye on this one, I got too confident. But I used drywall mud on the outside to smooth it out instead of bondo, and it worked GREAT! I was able to apply it without a mask and can even use gloved hands to apply it. I still used a mask to sand, but I only needed a fine grit to smooth it out.
Now here comes the best part for those worried about it getting wet. I used plasti-dip spray to waterproof and seal the helmet. I washed it down to test it out and no problems.
I am hoping I can blame the humidity down here in louisiana for the warpage, cause I am really getting tired of redoing this damn helmet. I want this sucker DONE for the halo 4 release dangit!!!
