Paint flaw correction is always an issue. I must say that if you're detailing by hand, it can be "challenging" to say the least to remove marring/scratches by hand. A "best detail" should include a quality polish, if needed. If correction is needed I suggest a PC & a mild polish. Otherwise, glazes can be used to "mask" some marring. VM,RMG,Revive Glaze & Creme Glaze are my glazes of choice when I'm using a carnauba wax. For polishes, I like Optimum Polish & the Chemical Guy's polishes. To me, Klasse All In One is more of a chemical cleaner for paint. It does a tremendous job cleaning paint & makes for an awesome base for any sealants/waxes.
Sometimes a "best detail" for the exterior is quite simply a good wash,clay followed up with Klasse All In One topped with Natty's Blue. It's an effective "quicky" detail. If you're a carnauba junkie like I am, try these carnauba's on for size........Natty's Blue,Souveran,P21S,XXX Hardcore Wax,Trade Secret, DP Max Wax,Meg's #26 ( or Meg's #16) Extreme Depth Carnauba,Butter Wet Wax & any of the ClearKote waxes.
For sealants, I like & use, try........Zaino Z5/Z2 Pro/Z8,Klasse All In One/Sealant Glaze,Wolfgang & Extreme Top Coat Sealant w/ 3x Carauba.
When it comes to Quick Detail Sprays, I use the following to maintain my carnauba wax finish.......Crystal Mist, Sonus Carnauba Spritz, QuickShine, Poorboy's Spray & Gloss & any of the Chemical Guy's qd's.
For qd'ing Klasse AIO/SG I use Sonus Acrylic Spritz & Acrylic Glanz.
For qd'ing Zaino, I use Z6 & Z8.
For other sealants I use QuickShine,Spray & Gloss & the CG qd's.
For your interior panels,consoles & dash I use IZ Cockpit Premium & Chemical Guy's V.R.T.. (sometimes 303 as well)
For cleaning exterior glass I use Klasse AIO, Zaino Z12 & AutoGlym Glass Polish.For interior glass cleaning, I use Sprayway,Bon Ami & Stoners Glass Cleaner.
For tires, I love Z16,WG & CG Clear Liquid Extreme Tire Shine.
For mf's, I use PakShak mf's,Sonus Der Wunder Buffing Towels & Concours Buffing Towels.
For exterior trim, mud guards,bedliners & door seals I'm now using the new Gel from Chemical Guy's. Teriffic products that seal/restores vinyl,plastic & rubber. (doesn't run after washes or rain, either)
These are just a few of the products I use frequently. So many products.......So little time!!
