Wudhu

Peel off nail polish

Q: I would just like to know if it is permissible to wear 'peel off nail polish' that you can put on after performing wudhu, and then peel off when you need to make your next wudhu, it peels off easily, also comes off in water. So would it be permissible to use and can you pray salaah with it?

Washing the limbs of wudu without wasting water

Q: When I make wudhu it takes too long at times as I feel I am not wetting or covering all parts of the limb I am washing. This is also causing the wastage of water. What can I do to ensure that I do not waste water and over wash? If I rub water over my arms or legs 3 times (and try to cover all areas of the arm or leg) but not every single hair gets wet will this count as still being wet and my wudhu accepted? I would say my arms and legs take the longest.
