I wonder if anyone has ideas for painting cast radiators while they
are inline. I'm on a deadline and cant afford the time to take them
out and sandblast them etc. How can I paint the inner parts, are
there flexible spray attachments or something that will work? I only
have 4 inches between it and the wall so I known it wont be easy, if
possible at all.

People paint radiators in place all the time**. Why not go to a paint
store and see what kinds of brushes they sell?

And the important thing is to decide on the color. IIUC, white and
light colors make them less effective, but I've been wrong before.
And although I asked once, I never understood the difference between
metallic colors and black. Afaik, they should never be painted at
all, because the paint stops the heat radiation and requires more
conduction first.

Or just dust them and buy radiator covers. They have a nice flat top
good for lots of things.

**We have to find those radiators and stop them.
