I am looking to strengthen up my cardboard helmet, but I do not want to fiberglass. I live in an apartment and the bondo smelled for a long time and the wife would not be happy if I stunk the apartment up after the fiberglass.
I used modge podge on the ears before using primer and that seemed to work pretty well, but since the helmet will be handled much more I was looking for a material to provide some strength to the cardboard. Looking for a material I could paint or spray on.
Has anyone used spray on truck liner?
Well I guess that is all for now!
Thanks in advance.
