Hey there,
I used some Rustoleum High Performance Enamel, nothing special. It'd be easy enough to strip down if needed. I also had their front bumper on and they both looked nice together. I sold the truck, that's why I'm getting rid of this one.
So at some point between putting the upgrade files on the ProCal and running the rack upgrade process it deleted the original rack files. The tech at FP asked for pics of a couple menus in the ProCal and came back a few hours later with a solution to plug the tuner into the PC without logging...
