OK, so i bought myself glue, and 2 colours of paint.
I will add papier mache first, and then sand, and then add a silver undercoat, and add some salt to some spots to create wheathering,
then add a blue overcoat, and remove salt. Will hopefully look pretty nice.......... HOPEFULLY
OK, so i kindof messed up a little, so i had to replace some pieces of the helmet, and spray it with a sealant, to prevent the cardstock from soaking in the glue
from the papier mache. Therefore, i was delayed, and cant start papier maching until tomorrow.
Paper mache works surprisingly well if you're patient. The biggest problem with it is the lines from the strips of paper not blending well. My paper mache helmet thread is in my signature if you're interested in looking, ODST helmet was just mache, the green and pink helmets got a layer of spackle. The spackle works very well in covering the strip lines.
And make sure you do plenty of layers, the 4th helmet my wife and I did was a wicked rush job and the helmet twisted like crazy. I recommend 2 full layers outside, 2 full layers inside, and 1 more layer on the inside just around the bottom ring of the helmet.
The last time I used paper-mache was about...22 years ago?
But what I recall of the paste we used, that it was a very watery substance, dries pretty fast and it kind of coagulates (ie. clutters) when left to dry in it's container without a lid. I remember we had to make a mask over an inflated balloon and when properly dried and painted, you could walk around in the rain with it.
I can't remember the name of that particular kind/brand of glue (who the heck remembers THAT at age 6).
