Has anyone had experience dealing with small rust holes? My dad says that I should just stick ducttape on the back of the panel and bondo over it, I have also heard something about fiberglass reconstruction. I can't mig weld nor is the car worth enough for me to invest in someone who could. Here is a picture:

It is on my rear quarter panel, roughly two inches by maybe an inch tall. Rusted straight through the panel. Any help? Thanks!
