Can anyone tell me if it is bad practice, when applying acrylic to do zone 1 and then file to shape before applying zones 2 and 3. I find that sometimes, on a bad day, I make a total mess when applying the white, and things go from bad to worse from then on. However, I have been experimenting on myself, and have found that if I file the white to a decent shape first, then zones 2 & 3 seem to follow OK . They don't seem to lift any more than usual (I often get lift when doing my own nails). I would like to know if its OK to do this, and whether I would need to leave the nailpure and primer till after completing zone 1, before considering trying this with a client
