when done correctly with the exact amount of cuts for a 90 degree angle you should not have to use fiberglass. simply glue in each kerf cut then bend each piece should touch each other. i always add a 45 as well to increase structural integrity.Did you glass the kerf or was the support enough? Nice looking box!
