bro u done the nice job...!
yes u will learn from time to time. you really need some more concentration on it if u can because the detailing is not that easy as it can be pronounced. detailing member of pw are serving hours even as experienced person is serving days to get her ride detailed. so next time you be carefull during washing process.
I cannot state that u have not done the hard work because the results does not only depends upon the work it also depends upon the car condition. but this statement only applies to regular type car care taker but some of our guru jees like durrani sahab he can change the condition of a car after all he is papu detailer.
