For ejector pin mark holes, I like using Vallejo putty (white and fairly non toxic) by specifically filling the hold AND also creating this ice cream top shape, because the putty tend to shrink, but with a small top on the stuff, I can let it dry for some hours, and simply cut the top off with a sharp blade, and just drag a sanding stick over to clean it all up.

I don't intend to use putty on this project, for one because I don't have any at the moment, but also because this is just a small starter to get back into building. But I will keep your advice handy for future projects, thanks.
