Might even be better to delay it even further so you can just keep painting indefinitely with a small crew.

That's what SF doesa with the golden gate. Want to say it gets repainted every 18 months or something?

I imagine you could just tape it, wrap it and then fumigate it with paint. Would go much quicker.

Someone tell me why I’m wrong

The obvious, much quicker way would be to drop the required 60 tonnes of paint from Canadairs in a fly by. /s

You’ll miss lots of nooks and crannies because you can’t convince the air currents to blow in every conceivable way to move paint around. You air movement apparatus will take on much of the paint, probably causing it to function in much less than an ideal manner. There are challenges with keeping the paint wet while moving it with air pressure.

You could probably get VC funding to solve these problems and then you’d be onto something.

Depending on how paint "wears out" maybe the parts you would miss are the parts that don't really need to be repainted.

I don't think there's any part of the structure that doesn't need repainted, or rain/dust will get in and tear it apart over decades.

> fumigate

I guess it'd be more like the electrostatic paint they do for cars. Negatively charge your object and positively charge your paint...

Where do you think “speed” sits on the stack-ranking of priorities for Eiffel Tower repainting/surface maintenance?

For a monument of its value, I would almost think speed/lower cost would be seen as red flags.
