fuel tank repairs

Ok as indecision always requires I did some more research both on my own and on another web site. All information out there comes to the same conclusion.(EPOXY) is the way to go. Polyester can and will work however there seem to be some adhesion problems with old polyester and new? I don't understand it thats just the research on the internet." polyester secondary bond" is the search I was refered to from another site.
The other issue that I discovered is that polyester cures and a chemical called styrene avaporates and leaves a (porous surface)? that flies in the face of sealing the wood by encapsulation. I am not somuch worried about the porous surface as the boat did last a few years already with polyester resins so the problem cant be that bad. the secondary bond issues though concern me as I am a novice amature with this boat repair. So on the chance that I do the snafu...... (hey iv'e done it before) I think I will spend the money for safty and piece of mind an order the epoxy.
