Hi all,

the recent batch of metal minis came in here, but unfortunately they are of lesser quality (apparently someone wanted to speed up the casting and used more mold release talcum powder than last time ).
The result are pittings on the surface. I already sanded it down, but there are a number of deeper holes that are rather stubborn.
How would you get rid of these? 'Tried priming, but they show below the primer. More primer obscures the details of the model. The primer is not sandable.
'Tried using the milliput milk method with more success, but sanding it down again seems to remove the stuff that covered the holes as well (washed the mini before to get the mold release off ofc).
Has anyone tried Mr Surfacer for this ? It seems to be the solution here, but I have not used it yet.
Any other suggestions maybe?

Sounds like pretty much exactly what Liquid Green Stuff was made for.

No, no, no!
Liquid green stuff was made for sub-par quality "Fine Cast" minis!

Suppose it would work though.

Or regular greenstuff.

Liquid greenstuff is easier for this specific purpose, but that's pretty much the ONLY thing that liquid greenstuff can do. Regular greenstuff can do a LOT more.

If fixing casting issues is the extent of your conversion hopes and dreams, then that's fine, but if you're ever going to want to do more, then filling gaps is a good way to get some easy practice with the material.

Clean and sand the surface before putting on Milliput. I don't find I need to sand it back. You can try putting on a thin layer (tiny amount) and blending it smooth with a wet brush, might work better than a pre thinned wash if the pitting is severe.

Edit: a brass brush in your dremel can be helpful, as can a polishing wheel.

I used a rubber wheel on the dremel for smoothing the surface. The mentioned pittings were persistent, they still show on the now very smooth surface.

Sounds like you want to skim the surface with Milliput then.

There is a rotary tool that jewelers use that literally pounds the surface to remove pits. It's basically a triangular shaped rotary piece that has rounded edges. You have to be gentle with it on softer metals. I will see if I can find it and post a picture of it later. The piece will require sanding and refinishing after use.
