Mine is pretty much as follows but there are plenty of ways people get good results
Id say first step always invest in a good quality wash mit!! they may seem pricey the bigger ones but the quality really helps to avoid swirls on the paint.
use of a tar remover or grime remover (i use dodo crudzilla first before a was to get heavy contaminants and break down traffic film before a wash)then rinse,
two bucket wash(one for shampoo one for rinse of the mit)
Rinse and towel dry.
Polish autoglym SRP always works well for me but i also like lime prime/microprime depending on budget.
followed up with black hole glaze by poor boys (as yours is black)
I like to have a quick once over with QD at this point to get rid of any smearing or residue.
Then its Wax (i uses purple haze pro by dodo myself)
Then a final top off with Red mist spray.
Obviously product of choice for me is Dodo with a mix of auto glym polish and poorboys but thats cause its worked well for me! try some new things and see what you can like to work with
good luck and enjoy! its addictive
