Wow you added a ceramic coating to a FIRST GEN MDX!?!?! ZowieI'm a north of your state border neighbor. MDX is 1st generation dark blue. I always use a very good local soft cloth auto car wash (not by choice - & yes, arguable if there is even such a thing...) with always undercarriage wash & the recently added ceramic coating (another topic...) & semi-annual exterior detailing. All that works for me. But again, it's 1st generation with battle scars. So, little scratches don't even show...
Not that I care; 18 years old with 160+ miles. I am surprised the ceramic coating works especially well for my MDX; get frequent compliments for such an older vehicle. But, I also know doesn't work for everyone. Like others here say, nothing beats doing the TLC yourself. But, if that's not an option...
