I would politely suggest shelving the Megs products and using Z-PC. Megs is not as fine a quality product line, especially weak in polishes. I only use Menzerna and Zaino for polishing. #105 is probably more aggressive than you need anyway.
OH I also added mud flaps front and rear to the car. The back I didn't really need but the front with the stick race tires is throwing so much shit on the car and if you get down below the door it's covered with small chips.
I tried other polishes but nothing is cutting down the micro scratches that as near as I can tell came that way from the factory.
I'll start slow with the 105 and see how it goes.
