There are a couple of products that I use for every mani. I remove all polish with acetone, then I use soap and water and a nail brush to wash my nails off, then I use a prep that I picked up at sally beauty, It makes sure all oils are gone before I start. My b/c of choice is borghese magnetico, I always have good results with it. I apply two coats of color (I tend to do thick coats so two is almost always enough) My t/c of choice is seche vite.
I have also recently become obsessed with cuticle care (since participating on the mua nailboard) Every morning at my desk I apply cnd solar balm and push my cuticles back. (I'm guilty of trimming them every so often too)
