    Right it might be strong as steel, but that is worthless if used on plastic properties. CA Glue or Duramix 4040 is really the answer.

I feel like it would use my current mold as a mold for the fiberglass, but I've never worked with this stuff before.
    If it's just surface cracks, then you would be fine doing that. If it's structural cracks then you will have to redo it, otherwise it will fail later down the road.

    Post pictures, most likely they are structural cracks unless you really have the bondo piled up and they are just surface cracks

    Yeah, I have to agree with these guys. My idea of drilling holes might be interesting, and could -- theoretically -- work. But if the JB Weld isn't grabbing onto the plexiglass, then I'd follow their advice and choose another material. Yep, it's extra work. But I bet you'll be happier in the long run.

    The holes thing would work sort of, and would create a better mechanical bond, but you'll want a chemical bond to prevent temperature cycle damage and retain flexibility.
    It would be a little work, but I think rebuilding the whole piece the right way would be better than having to redo the one you have now.

    I can assure you that they are structural cracks. Does anyone know of a glue that would bond plexi glass? I used plexi because it was easily available, so I would like to stick with it.

    acetone will work to bond plexiglass. or better yet take some scrap, dissolve in acetone, and use that as a glue. glass jar or a PP bottle works well as a container. remember to use real acetone, and not fingernail polish remover. you can buy it in the paint section of a hardware store or homedepot.
