1957 vintage metal 2 storey mobile home Reno

We found this vintage TravelMobile home for free and in serious need of repair , the entire inside was partially gutted and the rest needed to come out due to a roof leak and mold and rot, the entire outside shell and inside louvre windows were metal and in desperate need of repair , the only product that would work to loosen and clean the metal on the windows which there are 18 of them was WD40! It was a life saver and without it we would not be able to have renovated our now forever home, we used it on everything in the trailer as it was all metal , we used it to lubricate the window mechanics , we used it to loosen bolts held on for over 60 years! We used to to lubricate the tire bolts to even move the project to our property in the first place ! We used it on the front door jams to get them to open up to even get in the house at all! Without WD40 this project would have been a non starter ! It was the only product that worked and even helped to clean the outside of algae and mold from sitting in the woods for over 60 years ! WD40 is a miracle product that if it can fix this old house , it can do anything ! Thank you
