Epoxy resin is much better than polyester resin for a number of reasons.  It is much safer to use as the fumes are far less toxic,  it sticks much better to damaged surfaces and is totally waterproof unlike polyester that can be porous especially if fillers are added.  I use West system epoxy for repairs as it is easy to use and reliable, but any good quality epoxy resin will do the job.
