Why airstream restorations are so slow

This is my house Lilly's Rest. The front part you are seeing was moved onto the stone portion in the rear around 1870. Over the past 10 years I have have been doing one major restoration or remodeling project after another. This year we are residing the house. This is what is keeping me from making serious progress on Anna.

I have been removing the clap boards which are just nailed to the studs. Insulating, installing sheathing, and vapor barrier. So far I have about 70 % of that done. Next step will be trim and siding. I have been only able to put in small chunks of time polishing, but here is where I stand...

You are looking at 100 hours minimum here. As you can see, I still have a ways to go on this "first cut"

The bottom of a pound. Good thing the folks at Vintage Trailer Supply treat me so good, a new pound arrived just today along with some other vintage goodies.

This area has taken a long time due to the heavy corrosion caused by someone using steel wool or a very heavy grit sandpaper. All the scratches have created thick oxidation that  feels like sand glued to the surface. The stuff is extremely stubborn and requires a lot of effort to get it off. I have been using 320, 400, 600, 1000 wet dry sandpaper followed by F7. All the detail of the door with in the door, and the door itself had also contributed to it taking so long.

Even with wet sanding and multiple passes of F7 I am left with a surface like a tangerine. I feel this is about as good as it will get. Beauty marks, age defining lines....
