Bondo strength?
(1/3) > >>
MYX:
I have used bondo a lot on cabinet repair. It is great in situations where there is water damage or things like that. But I need to make something that I can squirt into a mold and it is something that I think will take some abuse. How strong is bondo as a stand alone structure. I figure it will be about half an inch thick and about 2 inches wide and 5 inches long.
Or is there something better I could use? I do not want to pay a ridiculous amount and I already have bondo (which is why I was asking.)
Texasmame:
What are you casting?  What will it be used for?  Bondo is pretty strong stuff but if you wanna get real good strength for molding some part, try using some of that "steel putty."  Mold it, let it dry *at least* 24 hours (don't fiddle with it prior to that).  Should be fine.
Tailgunner:
Sounds like a job for Alumicast, but if you want something you can get locally I'd suggest "tiger hair". It's basically bondo with strands of fiberglass mixed in to give it reinforcement.
spooky:
Do not use Bondo as a structure. Its made for filling and is only good for a quarter inch.After that it gets brittle. Kitty hair type bondo is stronger and has some fiberglass resin mixed in usually but still not what I would use to build something. If you could give more insight in to what you are doing I may be able to help you further. I am a paint and body man so I know a little bit about that good 'ole Bondo.

I used to work at Arizona rentals , years ago
we used to fix risers ( stage's for bands) with bondo
I am talking the hole coner.
we would put in a thin sheet of metal under the riser (the missing section)
fill with bondo. dry, sand and paint.
Pink Floyd used our stage .
the news casters used our rised at basketball games.
never a problem

I think alot of things here use WAY OVER KILL.
