I was a little shocked today when I saw the pictures the restoration shop sent me of my 1967 Eldorado Repaint Project.
While the exterior of the car did not have much rust I was surprised that the front floor of the car had quite a bit of rust.
Some of the previous owners seems to have tried to stop the rust on the floor sometimes in the past by applying a good amount of rust converter, or whatever the black paint was , he applied over the rusty floor.
It seems that it did not help but just made the sheet metal oxidize underneath this sticky mess.

The restoration shop now started to remove this paint just to find some weak metal with some holes in it.
This is when they decided to cut the entire front floor out and replace it with some fresh metal instead.
They had to make a patch panel from scratch as no new panels are available for this car anywhere. The new custom made replacement floor was now welded in.
Like on the factory rubberized undercoating was reapplied underneath the car and the welding seams were sealed with seam sealer.

You can see all the detailed pictures in the restoration gallery here.

I hope this was the last unpleasant surprise for a while…

This showed up when the carpet and the seats were removed…

After removing the black mess, the weak metal and some rust holes showed up.

Unfortunately the original floor had to be cut out…

Big hole in the floor.

A new custom made patch panel is fitted and will be welded in.

The new panel is completely patched in.

Seam sealer was applied like it was done at the factory. In the factory they just painted over the seam sealer. We will do the same here.

This car came with factory applied rubberized undercoating which was re-applied over the patched floor.
