I had an oh shit moment when I saw PA plates.
Also, we should touch peens on being purple subframe buddies. Mine was called Dormant Purple but it looks just like yours. I'm kinda on the fence on my color choice as I did Dormant purple on the rear, and Jamaican teal on the front.
I would def scuff/sand/grind down the area around the subframe and paint & undercoat it. Eastwood internal frame paint on the unibody rails. Trust me, it looks good to have a shiny purple and gloss black reflecting on it.
I used rust bullet but I didn't want to leave it with their gray so I used their gloss black top coat. It's the tits.
