I use Sonus products a lot and really like them. Their polishes SFX 2 and 3 are superb on soft to medium cc. The clay is also great for regular maintenance. The leather cleaner and conditioners are also amazing and they really restore the new leather scent rather than using heavy perfumes that don't last. The Cockpit Detailer and Total Eclipse leave a clean matte finish. The All in One Cleaner (
APC) works very well on the interior and exterior without discoloration. I strongly recommend this line of products, though it is a bit pricey. Last week I tried their Carnauba Spritz (QD) and I was impressed, it left a nice gloss and also added depth to the paint - it is similar to Pinnacle Crystal Mist.
