This lamp was not in a good condition. I needed much patience to restore it, and there's a recipe below.

Remove all paint and rust it with sandpaper from disassembled parts:

The paint was of a very high quality :) I made all that was possible:

Now apply primer on metal. This is best done with a sponge, it will help to reach all places.

Leave to dry.

When it's dried out, proceed to paint.

I wanted to shabby the lamp and slightly rubbed it.
All is done! The beauty is ready!
