So I used some naval jelly to clean out some rust in my rear cab corners because I couldn't get to it with any kind of scraper. I then rinsed it off and let it dry and sprayed on some 3m rust encapsulator that was supposed to turn black within 20 minutes but it never turned black. What did I do wrong? What should I do?
