Naval Jelly
I have seen, but never used, a product called Naval Jelly. A few years back a fellow up the street was painting it onto spots of rust on his boat trailer. It turned the rust into a black crust, and then he spray painted over it.
Question: Does one need to wire brush or buff off the crust before painting, or can you just paint over it?
