unsuccessful [SEP] the brush on the double duty gel is cut wrong it has a chunk missing in the middle making it impossible to get smooth all over coverage which messes up the entire process i ve been unsuccessful in getting a good application and the second time i tried to open the gel it was sealed shut once i pried it open it s too gooped up to use i bought this kit to give revel a try before buying a full kit and i can t say i could bring myself to risk spending on a full kit
