Polyester or vinylester resin is not reccomended for repairs to fibreglass because the bonds are poor. But it will stick well sort of.
Most people use epoxy when bonding things to cured fibreglass.
It comes down to spending a little more to do a proper job looks like a quart will do it so an extra 40-50 bucks.
