Default Birdcage checking questions, rust, looking for

Without dissembling the car, where do I look besides the VIN area, and inside the Kick panel air vents for signs of possible rust? Typically, if the frame is spotless, no evidence of even surface rust, I look at VIN area, and poke around in the kick panel area, with a flash light to make sure condition is appropriate.

Any place else to look, check, that is accessible without taking the car apart? The under dashes on the C3 with A/C is much more crowded than C1 or C2 cars I have experience with.

So far, I have just looked at AZ cars with spotless frames, so a cursory BC inspection was all that was warranted; I am going to look at a car tomorrow that has a MO/IL history, so a much more detailed inspection should be done, i think.

Thanks,
Doug

Hi Doug,
If you get on the ground you can see a little bit of the rocker channels that are part of the birdcage and straddle the frame rails below the doors.
The frame blocks most of the view but you can see a bit. I'll post a picture with the frame out of the way to show you what you'll be looking at.
Another place to check for rust that's not part of the cage, but can be an indicator, is the lower part of the radiator core support. Do you now about that?
Regards,
Alan

If the owner allows it I would also remove the # 3 body mount cover plate at the front side of the rear wheels. A little difficult to get at without removing the wheel but can be done with a 1/4" drive ratchet and socket.

One thing about rust no matter how it looks it's always a little (or a lot) worse once you start grinding and cutting.

Also, you can shine a light up into the key holes of the frame along below the doors. Light surface rust is OK on the outside. But if you see rust on the inside of the frames--investigate further!

Here is one showing light surface rust on the outside, but the insides are clean.

That's a great point. Sometimes what looks like surface rust turns into pin holes and deep scale once you start working it with a wire brush or blaster.
