carnauba wax are used to get depth .but since you are ussing speed wax .which is worth the price tag but what else do you want from a wax which cost around 250 ruppes ? if you want some good depth first wash it with some shampoo . please do not use the shampoo which we use it on our hair .
after that clay it with clay bar for eg mother's clay bar turtle clay bar
then use any good carnauba wax for eg Meguries Gold class mother's carnauba wax .
use some microfibers useing normal cloth is like useing sand paper on you car
