1) Be sure that clean and wash your car properly , the best out there will be Meguairs Gold Class shampoo , u can get from "cheeho04" member from LYN, he do carry all range of meguiars product , i always buy from him because of service and also good price , don always looking for cheap price but bad service
2) Clay your car , no matter how new is your car , there must be some dirt that u couldnt see from the surface , claying is like using Scrub on ur face that scrub all the dirt away from your face

, after claying your car , u immediately will feel the surface is so so so so smooth like taufu fa

, not neccessary to get the Spray detailer with clay , u can actually clay with Meg gold class shampoo ,get a spray bottle , mix shampoo with water and u good to go , for the Clay bar u can either get the Meguaris Clay bar or 3M original JAPAN clay bar , from cheeho04 or lelong.com (me myself using 3M becasuse its much more cheaper than meguairs) , normally we clay it every 6 month to 1 year per time

So to boost your wax , after wash ur car , u can using Meguiars Spray Quick Wax and it's so so so easy to use , just spray and wipe , that it , normally i will do it once for every 2-3 week , some will do it every week BECAUSE , u really feel very very smooth surface every time u spray the Meguiars Quick Wax. Re-Apply the wax for every 3 month
That the basic to take care of your car , for professional detailer there actually got more step to go thru , but i think that not really neccesary , once u wax your car , then u can really wash your car easily , and dry out very fast
Ur car is your baby , don let bangla to touch ur baby

, everytime i see people go thru those machine wash , my heart so pain because u are actually letting other to rape ur baby

Thanks for the very detailed explanation. So your advise not to wash the car very frequently to maintain the wax life.
I use my car as commute to work everyday and the road I use is very very dusty especially on rainy days if I happen to be stuck behind a lorry. It is really worst that after the dirt dry off, my car look like cover by mud. So, in this case if I wash just using water will it make the dirt go off easily? and only wash using car shampoo once a week?
So did you replace the Waxing step with the Soft99 fusso 12 month on your recent try out. I saw some of the youtube video you posted on that. It looks impressive outcome.
