I had a new client last night who wanted me to apply her own 'ibd just gel polish'. As I only use Gelish products I did manage to persuade her to have mine. The colour she had is not available in gelish and she has asked me to find out if I could use ibd with my gelish foundation/ topcoat ( I gave her that as my reason to not use hers as I dont know if it would be compatible). She has booked another appointment so could anyone advise if I could use the products together please?
