Every inch of the car was professionally detailed a couple years ago, including the underbody, engine, interior and paint. To maintain, I really only do spot detailing with Griots “Best of Show” and their Ultra Premium Micro Fiber towels. I don’t wash my car very often (usually just once a year) and I’ll do extensive air drying throughout the car, not just the paint. I just wipe the engine down by hand and once a year I’ll apply some WD-40 on certain parts for conditioning. For the leather, twice a year, I’ll do a light wipe down with Meguiar’s Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Gold Class Rich Leather. I kkke that it’s light and easy to apply. It also has a nice scent that quickly dissipates.
