While you have your ports out you may want to take the time to compound and polish the cabin sides. It's much easier without the ports getting in the way. I simply used Gorilla tape on the inside of the cabin to seal off the port openings then buffed away.
For the compounding phase I used a Makita 9227C buffer at 600-1500 RPM, Presta Ultra Cutting Creme compound and a 3M compounding grade pad part #05711.
For the polishing phase I used a Makita 9227C buffer at 600-1500 RPM and Presta Chroma 1500 polish with the blue wool Presta polishing grade pad.
