ohh mere jano bhai
congrats for having new car
blackbox having good masking ability so comes good on bit older car or paint surface having some imperfections thats reason v1 guided u for good natural wax 
black paint easy to get swirls , take special care while washing drying , any good natural wax will fill these minor swirls so dont worry 
apc stands for all purpose cleaner , 3m apc is good choice in term of price and its quality
