hi geeks im having trouble with gems on shellac iv tried all different technques to keep them on... glue, inbedding it in the colour then top coat over the top, inbedding it in top coat nothing seems to keep them on for 2 weeks. so im wondering if its just easier not advertising it. i had a women complain because some of her gems came off within a week and demanded a full refund! (obviously i didnt refund her) i just offered to stick more back on which took up time ect. iv bought sworvoski crystals but im thinking if i cant even get gems to stay its going to be a waist of money trying them?
