I've been cleaning cars since I was 14 and took it up 'professionaly' (no1 sees it as a trade but it bloody well is) when I was about 18 and did it constantly for 15 yrs and had my own very successful detailing shop (divorce finished that) and what you need to do is get yourself some zymol. I've been telling folks for years and everyone that tries it sticks with it. None of this polish then wax! That's twice the work. Use zymol 'wax' and use there wash and wax and you can get away with 1 coat every 3-6 months in between normal washing whether it be weekly of every few days. Google it

If your real OTT then they sell some 11k 'polish'
