It seems a nerve has been struck here. Nobody is insulting your wife! I realize people have their product lines of choice and that is fine. This reminds me of a ford/chevy debate. I have used 105 for almost 2 years before switching over and tried every new technique I could find. Other than dry buffing, 105 is not user friendly compared to newer compounds. The bottom line is there are much easier to use products. I don't use too much product and follow the instructions. Assuming everyone is doing it wrong is just ignorant of the facts. I am sure many do use to much product when they first start out. I have always said 105 gets the job done. I have done many cars and had awesome results. I just prefer some of the better compounds that have come out in the last year. I still use many megs products other than compounds and sealants it is about all I use. However I feel like many manufactures the focus on volume rather than quality. I am not trying to start a war here and neither is the op. People are entitled to their opinion. I came in with an open mind, tried many compounds extensively, and picked a favorite. I have been detailing for 20 years and love to learn new things and that is why I joined this awesome forum. The best advice I have is buy sample size bottles and see what works best for you. Do your homework before you touch a car.
