I love having painting fingernails. I also HATE having chipped painted fingernails. So unless I have fake nails put on (which I don't really like, feels a bit bulky on my hands) I only ever wear nail polish for a day before it gets chipped and I have to take it off.
However I just found a nail nail polish called Shellac by CND. Apparently is goes on like a normal polish but dries like a gel for a chip-resistant finish. It is about $30-$50 which is about $25-$45 more then I usually pay for polish, but if it does what it says it will I would pay that.
I will let you know the verdict when I buy some.
