I put some rust converter in my rear cab corner pockets. I am worried because it said to put on a second coat with in 20 minuets and after it turns black but it never turned black. I don’t know if it’s because the first coat was too heavy or because there was some navel jelly left on the surface. I hope not the latter. I tried to clean it off the best I could considering the location. I will see how it looks next weekend. I also found some rust on the interior where the door frame connects to the floor. Another set back
