2007 BMW 650i. I see this one every 3rd Saturday of each month. The paint is still about 95%+ swirl and defect free so I just added another coat of Opti-Seal to the 2 month old application already on the car. The car sees weekly tunnel washes the other 3 weeks of the month and the paint was still noticably slick and glossy two months after applying Opti-Seal.
I think another half stop on the exposure adjustment would have had the first pic perfect...
=================
2004 Porsche Carrera. Obviously a daily driver! Last detailed in early February, not sure how much it had been washed since but it was pretty dirty.
After washing and before the sun went away behind the clouds, I could see the paint still looked virtually defect free, so I simply applied 2 coats of Opti-Seal about 45 minutes apart.
