i have tried using the ibd builder gel to no avail. i use the primer, bonder cure and then apply the builder gel cure, or at least try to cure. For some odd reason that builder gel doesnt want to cure. Its like it wipes right off with alcohol swab. I use the uv light and cure for 3 minutes, so i do not understand what it is that i am doing wrong. I wanted to use it over tips that i put on and just ended up using my structure soak off gel because i had spent so much time with that ibd it was ridiculous, i am frustrated with the ibd system. Can someone plz help!!! That stuff is expensive and i want to use it!!!!!
