Hi all, I have been casting polyurethane shells out of a silicone mould and noticed micro pinnoles in the paint, I am aware they are a defect of the resin (moisture, not degassing) I am going to work on rectifying them with possibly using talc in the mould. But I was wondering if there is a fix to fill these pinholes, I have tried dolphin fine filler putty but I can't seem to get it into the micro pin holes.
