2017 Porsche 911 — ceramic coating is glossy but paint still got light swirls

BatteryDetailerCommunity StarterMay 10, 20262017 Porsche 911 Carrera SLas Vegas
2017 Porsche 911 Carrera S, about 95,000 miles. The coating beads well, but I still accumulated light marring. I assume wash/dry technique is the real issue. Which contact step causes the most avoidable damage? I would rather test this logically than replace parts.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Porsche 911, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Just my two cents from doing this recently. I'm in no rush to be a hero on it.

Useful. I'll report back after I verify that on my 2017 Porsche 911. I'll update if anything new shows up.

I'd keep this practical. Verify the cheap/easy branch on the 2017 Porsche 911 before a big repair or a big spend. That's where I'd start. This is from a 2017 Porsche 911 in Las Vegas with 95,000 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' Worth doing even if the car feels fine right now. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2017 Porsche 911 owner helps more than a generic diagnosis. I'd do that before spending real money. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.
