Well the horse trailer I am detailing has a mess with the rims. They are covered in some light rust/oranging so I wanted to fix them up for the owner. They arent anything fancy, just grey wheels...I can take pics later tonight if needed. Im looking to level out the rust, then paint them a hyper silver. How do I go about knocking down the rust, steel wool? If so...what grade should I begin with? Thanks for the help guys...this is truly going to be a huge makeover when comleted!
