In the last year I have owned both an 02 4-Runner and 03 Tundra in Jade Green. 1 from Japan and 1 from Indiana. Both had the same tendencies to show every scratch, swirl and defect. No differences.
I too am a fanatic about my vehicles. For several years I have purchased all of my car care products from
www.griotsgarage.com and have found them to be the best. The orbital polisher with #2 and #3 polishing compounds every several months removes the light swirls. No matter how careful you are, you "will" get swirls. The dark colors simply make them easy to see.
Toyota paint.....not better...not worse than any others that I see.
