I want to start painting my nails again, but with two small children and the washing up toil of daily life, chips and flakes happen pretty quickly. I don't want to go for gel/three week manicure finish (can't remember what it's called) because it ends up feeling really thick on my nails, which I don't like. I presume I need a good top coat to protect them - can anyone recommend something idiot proof for a novice?
