Thanks everyone!

I thought I was doing it wrong, ans wasn`t sure if it would cause lifting or something. Good to know ``pros`` do it like that too sometimes.

I actuallly cleaned them up a bit too much on some nails, so regrowth started to show siiner tan I would have liked, so next time I will leave a the whites thicker. I didn`t know there were videos, I have to check that now!
I paint mine vertically, I just have better control like that, and I am trying really hard to make sure to cover and seal the ends, so that is easiest for me.
Poppyseed, Solar Oil is nail and cuticle oil. I use a an oil by LCN, lots if companies make them. It will keep your cuticles lovely, and with all the soaking off in acetone, it will keep your nails moisturized too, so they don`t get brittle.
