Here are some photos of my 24 ft Wells Cargo, purchased in 2005. I took it out of storage recently and notice more stains from the screws holding the panels in place.
Decided to replace them with stainless steel. Bought 400 from local fastener supplier only to make two trips back as total neared 800 screws.
I used 2 Rigid Impact Drills, one to remove and another to install after cleanup was done.
End result, a nice clean trailer, no more rust stains.
