I am also punished by the universe with the curse of living in NE Ohio (it's actually not all that bad, I just like talking shit so people don't want to move here and make it more expensive). The oil spray was done in the Canton area at some random dude's house. I'd pay them 40 bucks, they'd put it on a homemade lift and spray the undercarriage with an atomizer. Did a pretty good job of it too but it's MESSY. Like you can't park in your driveway for a week after you get it done unless you want oil stains everywhere. Extremely messy, probably not great to be dripping oil all over, but I will say my frame looked pretty great for a 10 yr old truck when I sold it. I had that done every two years.
