I have a 19 MDX Adv hybrid Fathom Blue Pearl with Graystone interior since March/19. I gave Ceramic Pro for all interior surfaces (all 3 rows of seats, dash, armrests, center consoles, doors, carpet, rear hatch). It is suppose to last +3 years; but, I have to do the driver's seat every year for $30 because of the extra wear/tear. So far, just a damp lightly soapy lint free cloth to clean the interior. The interior look fresh off the assembly line (only 4400 miles and empty nesters).
The price was wrapped up in adding ceramic coating to the rims, windows, and paint (I think it was around $200 for the interior).
