Spent hours today cleaning the undercarriage of the Buick. Long winter with not enough maintenance washing. Spring undercarriage wash was a bit longer this year. Thank goodness it doesn`t look bad after cleaning. The odd thing I did was put cmx on the muffler. You can see the muffler when walking up behind the car or following it. It`s a black muffler that quickly looks horrible. I guess I`ll see if it can take the heat and if it helps keep it cleaner.
