Ok, So I have used polystyrene for a helmet, but I can not get any glues to stick to it. However I have heard other say that super glue sticks to it like a dream.
So please, and of you experts, riddle me this.
Are there different types of styrene or does it need to be treated with something to make it glueable?
For example the following glues just peel right off when dried.
Resin (As in fiberlgass resin)
Now I have heard people say that 'it glues like a dream' when using the for sale signs, but thats not the case for me.
Please someone, fill me in.
