Steve -
I was detailing my fathers Express van, it's a green/blue with the shiny flake paint job and beside me was a brand new yet never detailed silver with shiny flake paint job VW Jetta. The paint felt like sandpaper and if I looked at the paint to see swirls the sun reflected off of it so bad that it literally hurt my eyes. The car was a dump yet it still looked better than anything I saw on the block .... before my fathers van was done.
I told my brother to look at the swirls in the Jetta and when he did his eyes fluttered like 1000 times per second, the sun really really hurt his eyes from the flakes, I was laughing my arse off and he was seeing dots.
