Seeing as I've been asked many times before about how I keep my polish looking good while spending so much time in the water, I thought I'd write up a short post about the products I like to use :D
First off, I will say that personally chlorine doesn't seem to affect my polish at all. It is more a case of getting chips when hitting the walls or lane ropes or other swimmers! Maybe I'm lucky, but it must also help I change my polish very regularly... although I've worn China Glaze Blue Sparrow for 6 days straight before with only a few small chips! Anyways, here are some of the products I love using:
Base coat: I usually pick between Barielle Camo and Sally Hansen Nail Quencher Hydrating Base. I've used Nailtek II Foundation and Precision Base a few times and they were ok, but not my favorites. I've also recently received Seche Base but haven't tried yet.
Top coat: My favorite top coat remains Sally Hansen Insta-Dri. Other ones I sometimes use are Sally Hansen MegaShine and Oh So Wet, but I usually only use these after my Konad. I remember reading that Poshe is supposed to last longer in chlorine than some other t/cs, but I've never really like it personally. EDIT -- My new favourite is Out The Door, and it wears really well for me :D
So these are my personal favorites, and they seem to work really well for me at most times :D Let me know if you have any questions!
