noob here but i did my own every week & in fact, i've the passion of indulging such vigorous hours in my car. Below are my weekly chores, 2 cars, 1-silver & 1 pear white:
1st step: mequiar's nxt shampoo (if budget restraint, i'll use magic 101, wash & wax)
2nd step: mequiar's quik wax (if budget restraint, i'll use turtle wax, wax it wet!)
3rd step: mequiar's swirl x (for my pear white color, i'll use caplan, tar remover for whole car body!)
4th step: mequiar's ultimate quikwax (sometime using simoniz instant wax, quick shine)
5th step: mequiar's interior detailing

all the above are spray nozzle type except shampoo & swirl x for time cutting consumption as all by hand only. the gleaming result won't last for long but at least i wash them both every week w/o failed!

i am ready & open for feedbacks/commments to improvise my result even better. pls share
