I been hearing alot about this bondo stuff (I'm new to car repairing )How good is it? Does it fall apart after a while? Is it a good idea to fix rust holes by putting a piece of sheet metal on the insde and bondo on top to make it look like there was no hole and just painting over it?

Bondo is great stuff....................however, the less you use the better. If it's too thick it will fall out, crack etc.

Rust will still form underneath it, so make sure any repairs are done properly, before applying the bondo. It should only be used for minor imperfections, not filling big dents.

What about the bigger holes?

Bigger holes.....you need to weld in patches or repair panels.

Bondo will not repair them, it will fall out.

Look at "bondo" as a "smoothing" tool, NOT a "repairing" tool.

If you were really after a cheapie job you could use a fiberglass reinforced "bondo" and if you clean up the rust good before it will do amazing things. HOWEVER, this is miles from the right way to do it.

By the way "Bondo" is a brand name, like Cresent wrench or Kleenex. It is a common slang term for "Plastic filler" or "Polyester body filler". "Bondo" brand is most found in the "McAuto" stores like Kragen or Pep Boys. It is not a bad product, but usually "retail" packed and VERY expenisve.

Evercoat is probably the most popular brand and is very respected in the auto body industry.
