Beautification

Q: My husband really likes red nail polish on my hands and feet, but I also want to pray properly. I have to remove my nail polish every time I make wudu, which is becoming very difficult. 

I’ve heard about halal/water-permeable nail polish. After making wudu, if I apply it, can I pray with it, or does it still need to be removed before every wudu? Or can I put it on after shower or wudhu and keep it on till next shower? 

Please guide me, as I’m very confused and no one has been able to give me a clear answer.
