It's not that easy. I use a rotary sander work up through grits 80 -> 400. Roll on primer to seal it and stop it absorbing different amounts than the surrounding. Once you can build some primer on it you can undercoat and build on that.
I've tried in the past with filler etc but it'd very difficult to conceal.
