I used lye and corn starch to make paint remover and stripped my M-37 military truck to the bare metal. It worked great. As noted, vinegar is the neutralizer for lye. After I completed the job stripping the paint, I put vinegar in a pump up sprayer and sprayed the entire truck. To my surprise, I had rust all over the truck surface. I now have tried to re-wet the surface with various solutions(ammonia, various heavy duty cleaning agents, wax remover )with no success. When I spray vinegar on the surface again, it does dissolve it to the degree I can remove some of the rust with my power washer. But in doing so, I just get more rust wherever the vinegar goes. It has become a nightmare. Any suggestions as to what I can put on the surface that will soften the rust enough to power wash it off without continuing to cause rust.
