Fiberglassing problem
Not sure about the CA idea or possibly using water based poly-u as an under base. Myself, I would just use epoxy resin after getting all the un cured polyester off... then continue on with epoxy resin for the remainder of the project.
I use a resin that I buy at the local hardware store. There is a bit about the product and its use on my F-4 page of my home site.
