So this ist is - my first built mandalorian helmet.
I chose to have a Pepakura helmet as base, the file is from http://www.therpf.com/f79/fierfeks-star-wars-pepakura-file-development-122071/
It was a lot work but totally worth it
To give the helmet its first strengh, I brushed it with something called "Eboxidharz", a clue made out of 2 components
After letting it try, I layed out the inside with fiberglass and now only brushed the inside with "eboxidharz" again. Due to that, the helmet become really solid
That is how it looked after letting it dry
Adding some stucco-spray was unnecessary
To get a fluently and smooth surface, I put filler all around the helmet, after grinding it once I did it again with some finer filler
