Need Books on Repairing Fiberglass Hull

I would like to get some recommendation on books / videos / web sites
that focus on doing major repairs on fiberglass boats.

I want to learn what are involved in making major repair on fiberglass
boats to see if these are something that I can do in free time.

If there are good books on doing minor repairs on fiberglass boats, I
would like to know too.

I am under the impression that we are better off asking metal workers
to fix problems in aluminum boat hull. Therefore, I only ask for books
on fixing fiberglass boats instead of both fiberglass boats and
aluminum boats.

I have already checked local big name book stores, and I cannot find
anything other than books that deal with minor cosmetic repairs and
maintenance. And I am hesitate to buy books through mail order without
skimming through the books or without other people recommendation.

Thanks in advance for any info.
