Sorry I have been gone almost a year. I have not finished the daft punk helmet, who knows if I will. If I ever do, I shall post it here. But, I am leaving this thing here as an archive to help anyone who ever want to build their own helmet. And if you even have any questions, I will be happy to answer or point you in the right direction. Best of luck.
Good alternative to bondo, apparently.
Here is a visual example of what to do before bondo:



This is good advice if you don’t want to buy chrome or any paint and want a decent shine on your helmet. I’m sure it works for both helmets as well. :]
Visor help from the forums. :]
Help with fiberglass~ (from the forums of course)
Help for making the visor and the LED for Thomas’s helmet (from the forums)
Sanding and primer help (from the forums)
Vacuum forming information (in case you wanted to make Guy’s helmet too). :]
Another alternative to bondo I suppose, haven’t tried it myself, but could work: “1/2 cup of plaster of paris with 5 tbsps of resin, a small amount of water and catalyze w/e 5 CC = instant bondo putty.”
Steps in forming everything using the baseball helmet. Good advice.
Progress of other user from the forums; pretty good visuals if you are using luchofunk’s files. :]
Alternative to epoxy putty, called Apoxie Sculpt. Apparently its better than wood filler, which was what I was gonna use, but I might not now~
