21' GMC 2500 Sierra Denali (latest pickup)

[SupremeAboriginal]

Just bought a 21' Sierra Denali 2500. Im new to diesel trucks...i got the truck for basically a $10,000 discount compared to others with the same mileage/year/trim. The only catch is...it has a good amount of undercarriage surface rust because it came from Canada. Nothing too bad (as of yet) but i do want to take my time and do my research on how to rid the rust and protect it from getting rusty in the future. If anyone has any suggestions...please, im all ears. Thanks. Nonetheless, its an excellent truck!

Spray the undercarriage with Fluid Film.. I've used it on rusty looking F150 rear axles. From rusty to black in about a week.
