:):confused:I had to remove a small oil based paints from the kitchen ceiling as it was painted in error. It now has left a tiny visual differences between the large normal level and the removal of the oil based paint. How do I fill it in carefully so thin without it being visually known to look like same level and repaint to hide it.

You could go over the edges of the area with sandpaper or steel wool to blend the new area into the old to make it less noticeable, then repaint.
