To get the best effect apply a full cure top coat over a gel or acrylic base. We suggest Light Elegance Top Gloss or JOSS Reflective Seal as the full cure base. Then apply a small amount of Rainbow Chrome with a disposable eyeshadow applicator until the surface is smooth. Remove any excess pigment and then coat with a gel topcoat. We suggest Light Elegance Super Shiny for the best performance. Remember to cap the free edge of the nail when using both the full cure topcoat as well as the finishing gel to get the best finish.
