Filling nail holes before painting

Alter_ego

Had a new shed a few months back. It was pre treated so we have waited a while before deciding to paint.
Problem is we want a decent paint finish so need to fill all nail holes. Can anyone recommend a filler that wont shrink as it cures or fall out?

I wouldn't bother filling nail holes when painting a shed.

If it is a good quality shed and you use the correct paint, it should look fine.

Maybe you should dab a bit of metal primer on all the nail heads.

It is a good quality shed, that was my next question - What is the correct paint?
