Guys, I'm a newbie when it comes to car care. In fact I have never apply any car care on my previous car ( proton saga ) until I got new car recently.
I realized my car will have lots of rain marks after rain. And the anti scratch material will have lots of rain marks as well. Is there anything that can prevent the rain drops retained on the surface of the car?
I saw in the facebook whereby the person pour lots of water on the car, but leave no water on the car surface. Can anyone know what this is?
Welcome to the thread!
To answer your question specifically, I believe most of the videos u may have seen would probably relate to wax, sealant or coating of some kind. All these 3 items are actually protection for the car paint, and they vary in terms of shine as well as durability. However, all 3 of them can do what u called "the person pour lots of water on the car, but leave no water on the car surface".
Perhaps for a newbie to try is to buy a simple tub of wax to start. It doesnt really have to matter what brand of wax, but start off with a simple tub of wax. Watch some of the videos on how wax is applied and try it on your car.

Thanks for the highlight sponge is the worst.
Tmr will go look for proper wash mitt.
I saw a article once about the wax should apply after x time of car wash to rebuild the layer, how to count ya?
Agree with douglas_tong, sponge is bad. During my newbie years of car detailing, I learned it the hard way.
Mmm, there is no formula on how many x times car wash then wax car again. It really depends on the wax durability and the weather condition that your car went through. If u use a cheap wax but your car hardly goes out in our weather, then ur cheap wax still last longer. If u use an expensive wax but everyday car parked in sun and rain, ur wax will still die very quickly.
From my personal experience, evaluating the presence of wax is a guesswork and also what u see. The most common indicator of wax durability is water beading (water turns into ball shape on your car and roll off easily) and water sheeting (the ability for flat water to slide off your car). U will have to google and youtube these examples to get a better idea.
I would say for a no brainer newbie way of waxing is wax 1 time every 2-3 months during hot season, 1-2 months during rain season. Just my 2 sen, hope it helps.
