So I have a Uhaul Valley hitch that is severely Rusted up. Its only two years old! I noticed that the weld on the hitch was showing some rust. So I started to scrape and sand and before I knew it I had removed 1/3 of the paint. So anyway I wire brushed it with a drill. and coated it with rustoleum rust converter. This stuff works great. It paints on white and turns black when its dry. It says to wait three days for paint. I bought rustoleum spray paint. But im not sure if it would be better to brush it on? Any suggestions. So rustoleum also makes a black hammered finish spray too. What do you guys suggest for durablity, rust prevention, and looks. I know some of you guys have experience with this stuff. Thanks.
