Dreaded Rust..

[Sdp1234]

Took off another 2 inches. Looks real clean on the back. But... the actual back of the sheet metal skin still has some rust. Plan to go up 1 more inch and remove the wheel well liners to investigate. I don’t want to take out too much more. Looking for a 2-4 year fix


This is the back side of the skin I removed
Arrow is at the top. Seems like water from above? Or maybe it didn’t drain?

Looks like you are making progress, but i'm not surprised that you haven't found clean metal yet.

In talking with a buddy who runs a body shop, he said the extra sound proofing material they put into the higher trim packages on Denalis and Escalades is one of the biggest causes of that area rusting on the NNBS vehicles. Might have the same thing going on on your vehicle. Said that the sound proofing material soaks up moisture and holds it and by the time you see rust on the outside, the back side is destroyed.

Hope you find clean metal sooner rather than later.

Removed another inch or so Looks like I’m past the bad metal.

Now I’m going to clean up and start the repair

What about that rusted inner rocker piece?

The inner rocker panel is not as bad as it looks. I’m grinding out (flapper wheel is taking most of it out) and using an encapsulator. The metal is still very thick, mostly surface rust

Welded. Not beautiful but I have some finish work paint and the Denali trim to finish up

Is that hidden behind the Denali cladding?
