It's a so called "paint deep treatment" that protects paint efficiently . It consists of five phases. First is complete cleaning of car (in my case it took over two hours ! ) then it is fine polished etc...swirl marks are removed etc...
Last one is so called "top coat" . They promise that resistance against stone chips is improved by 75 % . They also say that after ditec-treatment perfect shine is maintained for years. They give 6-year full warranty. It has nothing to do with wax which in many cases lasts only for couple months.
Best thing about this is that car is very easy to wash. They also say that this is best system on market
At least I am very satisfied !
