Repairing minor plaster issues

[ThePistol]

hi,

In preparation for painting a wall, I sanded out some defects and the darker test patches. However, I've obviously been a bit heavy handed as I'm left with some quite visible 'scratch marks' now the first coat of paint is on.

What is the best / simplest way to deal with this before I carry on with the painting? I had though about using some filler but concerned that won't hold very will given the marks are quite thin / shallow.

Thanks

Thanks - will give it a go!

Would I get away with trying to fill it flush, or should I overfill slightly and sand it done again (with a finer paper..)
