Thanks for your feedback! I am glad to say that I managed to deflock her completely, residue and all 🙂 I used nail polish remover without acetone for the eyes, blush, and cutie mark areas, which did not damage the paint at all, and acetone for the rest of the body, as it is more efficient than the non acetone and made my life easier. Of course I washed the pony thoroughly after to remove the acetone.
