This product works as advertised and that to me is fantastic. For under ten bucks I was able to repair the defogger. You must have patients when you do the repair. Also make sure you clean the tab down to the silver or copper that is very important. Find a different area on the edge of the grid to attach the tab and after 24 hours coat the tab in the copper fluid. total wait time for me was 48 hours and it has a solid seat and just in time we had a down pour with high humdity and the window cleared in about five minutes. Just take your time and you can save yourself big bucks in repair costs. Now if the auto makers can just build it better!Brian in Cleveland.
