im considering putting some kind of undercoating under my 07 crew cab. i was under there yesterday and noticed some parts showing some oxidation.

what should i use? Rattlecan?
what should i avoid spraying (heatshields) (wiring)? spend more time on?
Jackstands with tires off? tape off areas?

anyone have photos

 

I helped my father in law paint the underbody of an f350. I believe we used Rust-Oleum brand underbody spray. We painted it probably two years ago and after a Colorado and Kansas hunting trip it could use it again, but looked good for a while. MAKE SURE you tape and cover everything....no matter how careful we were black spray still managed to find its way places. All we sprayed was the frame, underbody, and axles. We did remove the wheels and sit the truck on jackstands Hope this helps
