Is bondo glass...strong?

[nametaken 10+ year member]

Well, i repaired this part of my box:

The dowel had disatached from the MDF, it was held on there before with some resin. Well, i gooped the whole thing in that bondo glass"kittyhair" stuff. But i was wondering if anyone had any prior experiences with this stuff being strong. I kinda feel it isnt strong enough, and since i havent put the subs back in, i could go over it with some resing and mat(ide have to but more resin though). I dont want to close eevrything back up, then 2 months later have this happen.

Thats what im starting to notice, i dont know if you can tell in the pic but i i knicked some of the kittyhair with my nails, and it sort of just cracked off, this is what made me weary, but since it wasnt that thick in that area, i figured the it could be stronger. but ill play it safe, 10 bucks is worth that feeling of security i think.
