Fixing Rod Boxes

[SURFERJRB]

I did a search and could not find anything. My rod boxes are beat up, cracked and I would really like ot fix them. Can I use epoxy, fiberglass, paint to repair? Or is there some thing else I should do to make them strong and new looking again?

My boxes are not square the one advertised on ebay will not work for me. Thinking to just cover with star board or something not sure yet any ideas.

OK I saw the post regarding "pole box" I am use to calling them "rod boxes"
