I have sanded the entire roof but only taking the rust spots down to bare metal. The naval jelly is working beautifully! Its pulling all the rust up off the metal. I have some pits thought where its just black not rust color. Can I paint over the pits? I see now what you mean Pat. I can not get the pits out with out warping the panel. Well , back to it it will be another 4-6 hours of elbow grease and sweat but its looking like its going to work. Just worried about the pits.... Thanks for the help and excuse my ignorance.
