    I need some advice on the best adhesive to use to repair the case for my bass. The case is a hard plastic Modulus case and has a crack in it. Can I use superglue or is there something else that's recommended?

    How bad is the crack? Superglue won't do this kind of job. Possibly some kind of epoxy. If it's truly compromised get a new case. If the case bit it and your bass is safe, then if did it's job...absorbing the damage that would have hit your bass. Protect your instrument.

    I just saw something at Home Depot today, that was some kind of fiberglass mesh impregnated with adhesive. I've also done repairs by combining JB Weld with a few layers of fiberglass drywall tape.

    Hi.

    If You can confirm (from Modulus) that the case is made out of ABS or another weldable plastic, weld it.

    I have welded several with great success.
    Some using a hot air welder, some with just a soldering iron if the innards are hard to remove.
    The beotch of it is to find a suitable filler material, but an old trashed case or an ABS dashboard or a bumper will provide a lifetime of that.
    Auto body shops carry ABS rod for welding car parts as well if there's one near You.

    IME no adhesive will work well, and short of laminating GF or CF patch, the gluing surface is too small anyway.
    Any adhesive remrants on the surfaces will greatly reduce the weldability as well ;).

    Regards
    Sam

    Agreed. I'd only use adhesive with a patch, to obtain sufficient gluing surface.

    Thanks for the replies. I'll try to get a picture posted tonight. This may help with determining the repair options.

    Unfortunately, Modulus went into Chapter 7 bankruptcy and is no more. Otherwise, I would just call them and ask.:(

    I would plastic weld it.
    A lot of sport motorcycle shops have them. They use them to repair busted up plastic body parts after a crash. I have used one a few times and they work great.
    It is the same as oxy acetylene welding but the torch blows a small stream of hot air that you can regulate and you use a plastic filler rod. The rods come in every color imaginable.
    Do a search for plastic welding in your area.

    As you can see, the crack is just below the latch.

    I'll definitely check out the welding option.

    Thanks!

    That would be a easy fix.
    Google it for your area and you should come up with a few.

    I repaired a large crack in a music man molded case using ABS adhesive and fibreglass matting. It worked great and you had to look pretty closely to even see the crack afterwards.
