Corroseal rust converter is great for areas that are difficult to get to and you are not sure if you did a good job removing the rust. It is a primer and rust converter for bare metal and tight surface rust or clean tight paint. It chemically converts the rust. It can be left as is, painted or primed and painted. It is milky white but after the chemical reaction is complete it dries black. I used this to repair and halt any further rust in some areas that I could not get to. Example: I swabbed the inside of the rolled top of the bed side. No way to get in there to sand the surface. This sealed the surface rust.
