Can you use nail polish remover to thin nail polish?

Yes you can use nail polish remover to thin out thickened nail polish. I do it all the time to thin out even the rock hard nail polish that i found under the couch that was years old. All you need to do is pour a little in the nail polish depending on the hardness wait a little while and you got nail polish you can use. When ever I do this it still always kepps its shine.
