Can you resin and fibreglass foam? I was afraid to buy resin in case it ended up corroding the foam. Then I'd be left with useless materials.
I went with craft foam cause it was easier for me to find, and reinforcing with muslin and Mod Podge. Seems to be working really well! Just a bit time consuming.
