I used Bondo to fix missing wood on the corners of my Turbo mini but I'm a little less than impressed with how well it adheres, I caught it just slightly on something when I moved it today and it flaked off cleanly without leaving any behind. :( I've come too far and put too much effort into this game to get skimpy on it now, so it looks like I'm going to be chipping off this shit Bondo and re-doing my work.

Shy of replacing wood what's the best way to fix corners so they're rugged? I'm leaning towards using Kitty Hair for the bulk underneath and a thin top coat of Bondo, but I thought I'd get other people's opinions first. FYI - whatever I use will be going over Minwax Wood Hardener, I don't know if that's with the issue with the Bondo was.

fibre glass?its all fluffy and uses a resin which will make it stick and its proper tuff stuff.

Bondo with less hardener... if you put too much hardener in it will do just as you said.

Also, make sure you roughen up where the bondo makes contact...

Finally, you could consider some corner protectors as well.

That's what I figure, Kittly Hair for what I remember is fiberglass resin and shredded fibers, so it becomes as hard as nails when it cures. The only issue I might see is how well will it adhere and how tough will it be to make smooth and paintable?

Good point, I'm a newbie in the worst way and it did harden pretty damn fast, so maybe that's what the problem is? How long should it take properly mixed Bondo to harden? As far as corner protectors go I doubt there are any that'll fit, these particular corners are not relatively square like most games.

Also make sure you remove any rotten/loose wood before you apply Bondo.

I always put a few coats of wood hardener on first to give a strong surface for the Bondo to adhere to.
 
I have a particle board cabinet that needs corner repairs. I'm thinking of trying somewhat course sawdust mixed with wood glue, or maybe sawdust mixed with resin, for reconstructing the corner; and then skimming Bondo onto that to make it smooth. Particle board is made from sawdust and resin in the first place, so I don't see why it wouldn't work. Has anyone ever done it that way?

Particle board is made of adhesives, flakes and resin.. but also a TON of pressure. Glue mixed in with dust will just end up being glue mixed in with dust :)

Short of cutting the corner out and replacing it with new wood it will be hard to prevent chipping if you hit it.. Either cut it out and *really* repair it, or be more careful moving the cabinet :)

Have you tried it? Course sawdust mixed with wood glue or resin to a stiff consistency, and allowed to dry would be fairly rugged stuff I would imagine. Pure dried resin alone is rugged in its own right. Add some fibers and you've got very rugged stuff (e.g., fiberglass) that can be sprayed and form a solid structure when dried. Wood (sawdust) is a fibrous substance.
