Anything below that was my contract. That meant nothing.
After reading this thread I was torn. Should I try to help out and show what these cars should look like new, or risk being called a show-off. Ah, what the hell, I'm a show-off.

My wife really hates it when I show off.

Hey Fred your leaf springs look painted. I thought original springs were unpainted? Also looks like a lot of the underbody on your car has surface rust, like there was no primer or paint used at all, or is that oxide primer? Very nice original looking car.

Hey Fred do you know what this bracket is used for. Nothing was attached to it on my car either.

Thanks Mike !! I was fortunate enough my car didn't have under coating and I brush blasted it with a small pot (Harbor Freight) sand blaster. I used Strip Eze on the fender wells and inner fenders on the sound deaden-er. As for paint I used PPG DCC single stage. I got a picture of my rear end and springs if you want. The spring paint was as close as I could get for the correct look of natural/blue hue steel for '69.

Mike Fred's looks just like the gray primer that was on my car and the Orange over spray from the factory instead of rust.

Ah, got it. I am used to my car's undercoating which is thick and gooey. They sure look different in their original state. So many under bodies have been restored. Here is what mine looked like. I am going with a restored look as the rest of the car is being restored.

Mike, it's a bracket for lone 6 cylinder exhaust pipe.

Nope, not rust. Original primer. But why some of it is a different color such as at the unused muffler hanger is a mystery to me. Anybody know why the primers vary?

But are they welded to all models?

I didn't know that 69's got the oxide primer as well. Don't see it very often.

Mine had the same as Fred's

As I inch my way towards the front of the car. The routine is: Use the heat gun and scrapper, followed by a wipe down with lacquer thinner, then use various drill bits and or Dremel bits to get to rust areas I can't reach with the scrapper or thinner.



Original underside paint. It appears that the entire underside was painted a semi-gloss black.



What I thought was grey primer is actually white overspray on top of the black base coat. Does this mean the entire car was painted black? Was it primer, or was only the underside painted black?



Frame Rails are in good shape as is everywhere under the under-coating. However there were some places that the under-coat missed, and those places have surface rust.



This area has the worst of the rust I have discovered so far. The rust comes off with the trusty Dremel tool and a stone bit.



This area also has surface rust. Notice the flap hole on the rocker panel. I had never noticed this before.



Not quite at the half way point yet. Here are all three stages, stripped to bare metal, original black paint, dealer installed undercoating. Hopefully moving forward I will be able to remove the undercoating with the heat gun and lacquer thinner only, and use less of the power tools. The grinding is the messiest part of the job and the most time consuming. As I move forward the surfaces are larger and flatter. I hope this will be reflected in the progress.

There's plenty of photos of survivor floorpans at CRG.

While apart run a wire brush or, flat wheel through the rear spring hanger holes and get them nice, clean and smooth.Paint the area to prevent corrosion. It will make insterting the spring hanger bushings much easier.

Thanks for the Tip Chuck I will do that.
