First off, I'd like to start by saying that if you have a rusty car, please please PLEASE don't fill it full of bondo and sell it as "rust free". Only reason it's rust free is because bondo doesn't rust!!
I did some more sanding, trying to get the whole car to bare metal, but i found a few spots with some bondo. So today i took the wire wheel to a few rusty/bondo areas and made some gruesome discoveries. The worst part of it is that i've only gotten to the top half of the car (from the tops of the wheel wells up) so far.
Now for the pictures. I'm not sure if it's worth patching it or if i should just get new metal since it's so full of bondo.
This is the back right quarter near the rear window. Yes that is mesh to hold the bondo.
Here's the back right wheel well. It's hard to see but there's actually no metal there at all. All bondo from the bottom up about 5 inches
Here's the front left fender up by the hood. There's no metal here either. I know there's bondo in the lower part too, just haven't gotten there to see how much.
And here's the weird discovery. As i started going through the paint, ridiculously thick primer, and the bondo, a steady stream of discusting water started pouring out from the panel. A good quart of it.
Should i just buy new metal? I'm not sure if it's worth the hassle to fix. I have to take it all of anyway.
