Gypsy....I use Krylon paint on my hitch and it works great. I use the black primer before I put on the top coat. Follow the instructions on the can..it will tell you how to prep the rusted surface. You are correct keep those metal surfaces painted and don't let that rust get too bad. It is not that hard and it makes for a better looking finish. Watch that overspray and don't get it on your truck or RV....especially on anyone elses!!!

Rusoleum makes a spray on rust converter now. It is black. Works well. Available at Home Depot or Lowes.

Highway Ranger,


I've seen lots of vehicles with lots of surface rust travelling around the country with no apparent stuctural problems. However, any kind of rust is always eating away, it doesn't stop.

Surface rust will continue to eat it's way through the metal. It can become a problem depending on the make up of the metal.

We spend a lot of time at the beach, the frame of our fifth wheel is spotty with surface rust. The seams on the cab of my old truck developed a really bad rust due to leaking roof top clearance lights. The sal****er had gotten in between the inner layer and the outer roof and began eating from the inside. I started seeing pin holes, one day I was able to push my finger through the outer roof. I've stopped all of that with the rust converter.

It's best to get rid of it. The rust converters work real well and then use a rust protective paint.

It takes about four easy days to do the underside.

Use the rust convertor before painting. You need to wire brush any heavy rust, flakes, dirt, etc off first. Then wipe down the area to be sprayed. Wear safety glasses/goggles and a mask since the rust convertor (neutralizer) is an acid. Apply it per the directions. Once it has dried as specified you can prime and paint right over it. The stuff works great. They key is to remove any heavy rust, flakes and dirt so you are attacking the rust at the root. Good luck and be safe.

Jack, do you know anything about Rust Bullet?  It looks pretty good.
