Prevent further deterioration of wooden Window Cills

[carpet_the_walls]

Hello,

The paint on one of my window cills has started to come off (see photos), and I want to prevent further deterioration of the paint, or damage to the wooden cill underneath.

This is the only window cill in the house which has this issue, so I was hoping there might be a temporary fix that would last until such a time as all the windows required repainting.

Thanks

It doesn't look too bad. Spot prime and paint it (using caulk as required).

I am guessing that the current finish is waterbased (given the sheen level).

Thanks for the reply and advice @opps. Not sure if the finish is water based, and not not sure how to tell.

Based on your advice, I plan to

1. Sand gently to remove flaked paint
2. spot prime
3. touch up with similar coloured water based paint.
