"We were called in to work on a high profile cemetery, next to the State Capital, where a number of granite headstones had been defaced with graffiti. Goof Off and a paint stripper from the local home improvement store had already been tried by the maintenance personnel and had left shadows on the headstones. With the use of Elephant Snot® and Shadow Max® we were able to completely restore the headstones. Your guidance and help were invaluable and you were a real gentleman in our dealings with you. Thanks for all your help."
