Hi there,
I use Shellac all the way to the final colour coat. I cure the 2nd colour layer, then use resin and activator to apply the crystals. I then used a layer of shellac top coat and cure as normal. I didn't find that it caused the crystals to lose their bling at all, when the light hits them they sparkle like mad!
ok maybe its the difference in the gelish top-coat or maybe I need to apply it more thinly, I'll also try the resin method. Ive also ordered the ECO UNIVERSAL SOAK OFF UV GEL TOP COAT that Baggybear suggested Good job I have plenty of fingers to try this all out lol, thx for the help
