Paint chips on corner of interior walls

[btcc123]

In a couple of weeks I will start painting the interior of the house.

I have a couple of queries,one is that on the right angles of some of the walls there are paint chips off the wall and looks like the metal corner plating that I can see.Whats the best way to touch this up before painting.

The other is that in a couple of the bedrooms there are some nail pops where you can see the nail head.Whats the best way to fill them in before painting.

The house has been painted before and is 15 years old.Thanks in anticipation of your help.

Fine sand the paint off the corner beads (very quick & easy) ready for new emulsion.
Re the popped nail heads. Firstly make sure nails are tapped in sufficiently by using a nail punch or something like a 4" nail.
Fill with regular filler, may need two layers.
