If you do the fiberglass, please save yourself the hassle and get gesso..The water/glue mix works in place of gesso for painting, but to do that with fiberglass you will spend WAY too much time and money on glue..Gesso will be perfect for the resin.
**My neighbor knows a lot about fiberglass and that's where I learned all I know lol
