fadh bhai
most welcome bhai jan and jazakallha for ur liking and greetings
or ye baat kyia ki app ne ? bhayion main mera tera nahi hota gee.
black is very difficult colour , i would say most difficult to maintain hehe but fully detailed ride in black having no comparison.
toyota black is solid col so give very high reflections while honda black is metalic so produce good shine.
swirls mainly apear on skin due to bad handling , i am not sure what detailing stuff u using and method. allways use microfiber clothes to wash, dry the car, never dry dusting the car skin as its main source of creating swirls , for washing allways use good quality car shampoo, since ur car is new so mother shampoo in gloden col very good and easily avilable in pakistan or meguir's wash and wax shampoo excellent choice.
we have 2 choices for swirls
1) hide them temporary
2) give light cut to car skin to remove them.
i prefer first choice. turtle black box is one of best wax solution for
black colour painted skins and its also fall in first choice i.e hiding
imperfactions
keep continue black box and try to avoid new swirls
