Bests & Worsts Reviews from Amazon

I have used the first can of six that I purchased and it appears to perform as described. I recently bought a 2015 Ford F-350 dually pickup from the local Ford Dealer here in Cary, North Carolina. The truck only had 3000 miles on it, but was sold as used and "as is". I should have inspected more thoroughly, as the underside is covered in rust! After much research, I decided on using Rust Oleum's Rust Reformer. After removing the rear bumper, I found the two attachment brackets to be totally covered in rust. I soaked these in white vinegar overnight, which removed 98% of the rust. I then washed in Hot water w/ Dawn to neutralize the vinegar, rinsed in water, dried, and then applied two coats of Rust Reformer. There were several rusted areas on the inside of the bumper, so I used a small wire brass brush on the loose rust, scrubbed with Hot water and Dawn, let it dry thoroughly, and then sprayed with Rust Reformer. The product covers the areas completely and is paintable with a Top Coat; Rust Oleum Gloss Black, after 24 hours.. which I will do today. This is the plan for the entire underside of the truck. I will update this review every six months to report on whether or not the rust returns in the areas treated.
