If raining season, it is good to have 1) a bottle of tap water and 2) a piece of 100% microfiber cloth (bought from Mr. DIY /Aeon) and keep at the rear car bonnet. Super White colour need super hardworking CAR owner to sustain cleanliness at all times..
You may get the microfiber cloth wet and.wipe the bottom of these aerokits (front, both side and rear ).. you can do it at work office car park / home / shopping centre.. Just 2 - 3 mins tasks while waiting for car engine ( cold blue indicator turns OFF ). For these few days, my microfiber cloth is always wet in rear car bonnet..
Installed rear DVR camera recording last 3 months ago.. Will have lesser tailgating AFTER every traffic light stop junction.. Because behind car driver saw it and DID not following yr car very closely anymore.. Actually, good to have front and rear DVR camera recording for any unforseen circumstances damage..
