Hi, I am sure you all have seen self-cleaning effect videos on youtube where a bucket of mud water is thrown on the car's hood. Good water run-off looks proven the theory.

Another thing, if we take photos of fully detailed and coated cars after driving around for a while, there still remains doubts about how much water-repellent surface will stay cleaner compared to an untreated surface.

Regarding the topic of self-cleaning characteristic, you might be interested in this case study, where I polished and coated just half of the car. For protection, I used 3 component liquid glass Zen-Xero Dynamic.

Please feel free to review my case study blog post about liquid glass coating for the car (14 images included).
