Most nail polish removers are like 99% acetone, im a wh40k player. Acetone will work all kosha on any actylic based paint perfectly fine. I dunno why Otaku doesnt know this ad hes a miniature painter too
As another 40k player, I can easily explain why he didn't think of it: he likely thought the nail creation thing as a completely different world and has never had any exposure to any of its materials, so he likely had no idea that nail remover was nothing more than acetone, hence him using the next best thing he could think of... acetone.
Not everybody has the ability to cross over from one world to another and see the similarities, so this manga will be about one person doing exactly that and learning from it.
