I currently do acrylics but wanting to get into gels and coloured gels. I know that coloured gels go over L&P but do you simply start applying coloured gel after using 150grit or do you still put a base layer of clear builder gel on first before colour?(Sorry, not been using gels much since training and totally forgotten!) Also with coloured gel infills, after filing down the colour a bit do you apply clear base layer to just the infill part or the whole of the coloured nail before applying the coloured gel again? I am using NSI coloured gels by the way. x
