amir bhai well i am quite busy now a days in office but its not mean any reduction in my detailing love. now a days i am also experimenting dust problem on black ride ( before i allways had lighter colour cars ).
one sunday i applied swissvax and forgot detailier wipe and after gujranwalla trip car was like bhoot bangla 
last sunday i applied dodo purple haze and did applied detailer wipe and had trip to faislabad on 1st may, this time results fair enough, here is pic on m2 from my bb but still not 100 % satisfy:S

on otherhand on white alto applied nxt last sunday and after 1 week results are still very good:D about dust. nxt really very good wax specially for our dusty enviornment, it leaves silky touch to car skin and dust particular simply dont able to stay at surface , extreamly happy with it.
tonight going to wash car and dodofied , tomorrow morning nxt on dodo than will share the results and pics inshallha
