I first received this bottle a few months ago but recent surgery has prevented me from using it. do this every 3-5 weeks. It took me about an hour to make as much gum as I could find on my truck. But worst of all, the damn bottle is useless. "You know, you can't unscrew the atomizer and stick a new one in a bottle of kitchen cleaner or whatever you've got. So you're stuck with a leaking atomizer and wasting 1/4 of it. I'll see if I come back, otherwise I'll have to cut off the atomizer and pour the contents into another atomizer! Just a big expense for an expensive spray bottle. I hope it works at least 3 weeks! :-(
