Questions about fibreglass
Alright, I'm planning to use fibreglass with my current cosplay project, but as this will be my first time using it, I need to know a couple of things from anyone else who's used it in the past.
Can fibreglass be used on cardboard, or does it (the card) have to be sealed with something first before I apply it? Also, I was told that fibreglass can't be spray painted without being sanded. Is this true or not?
