I regularly use this line on my water lines and the area just below. I find that it lasts really well. Not a 24 hour lasting , but maybe 6-9 depending on my day. I know it's a little on pricier side, but I find that if you spend a little more, you get a little more. Good luck!

it doesn't stay on the waterline and it doesn't apply true to colour on the waterline either. it's not worth $3, let alone $30.
