I'm getting some surface rust on my frame and trailer hitch area.

I've read some posts about POR-15, and I'm still researching that stuff.

I was just thinking that I'd scrape off any loose rust, sand it down a bit for a good scuff, and paint some flat black rustoleum on it.

Any thoughts?

 

your method would work just fine. POR-15 would be more durable but also more expensive, so up to you. definitely get that surface rust off though before it gets worse

 

I painted mine right over the surface rust with rustoleum rust converter, worked very well.

 

I ground down to bare metal on most of my frame rails, then painted with semi-gloss rustoleum.

Its holding up very well!
