Fixing Rust?

[civisi]

I work at a shop where we do rust prevention for detailing works. Mainly it involves undercoating the fender wells with spray in bedliner and it really keeps any rust from forming and it only is on the bottom fold of the metal so it would just be black. I don't know if you're planning on protecting future metal from rust but it might be something to consider. Also, there are other chemicals out there that help with rust in other spots of the car; that might be something to consider once rust is fixed???
