Fixing rust holes with filler??

Yea, I used rust converter and then Bondo-Glass. Kern we just want it to last about a year, so my son can save money for another car. This thing has 223,000 miles and a good bit of rust. Just looking for finishing advice from the point I'm at now
Exactly.

If it were one of our older cars.. then of course welding in some sheet metal would be appropriate.
