I completely screwed up my first master chief helmet for sure. I didn't put enough hardner in the bondo/glass for the front of the helmet,which i don't even use any more( only glass cloth and resin for me now). the second helmet actually made it to paint, with plenty of flaws but I was getting the hang of it (it's the red one). Three is fully glassed and four is coming along nicely , I'm happy. Yes I dig the mohawk I've put on top. I have also been using a vacuum when I do the dremel finish work on the glass and resin. It seems to bee working great for me.
