So with Gelish or Shellac, everyone says apply as thin a layer as possible, but i find that when i apply only one coat for the white tips, it's not opaque enough and quite streaky. But i really don't think i'd have enough time to apply 2 coats for the white tips along with everything else! I'm supposed to do a Gelish french in 15 mins in the salon i work in! (using the 18g lamp).
