Sometimes, light scratches are unavoidable. Hence, for every 3 to 4 months (some 6 months), a layer of wax is applied to "resurface" the clear layer and sometimes, the scratches are slightly deeper and touch the surface of the paint layer, waxing could "seal" those scratches and restoring a protective layer of wax on top of it. Wax is not a hard material, hence, it would wear off over time and won't help protecting against future scratches.

Coating on the other hand, is quite a recent thing. If you remember, last time there is a big rush to coat windscreen with something call RainX or some other brands, to make the windscreen hydrophobic and allows the water to disperse quickly when driving during rainy days. Those hydrophobic coating only works on glass surface. Hence, coating usually done by applying a thin layer of quartz (glass) on to the clear layer (or paint layer if polishing was done before coating or older cars), and then followed by a hydrophobic coating. There are cheap coating which only gives hydrophobic effect, and expensive coating, which have a certain "claimed" hardness level, 9H is the hardest so far. So this hardness will protect it against scratches. It works pretty much like Corning/Gorilla glass on certain smartphones, or sapphire glass on watches, the glass is hard enough to protect it against scratches. However, with enough force and sharpness of the scratching material (particularly lady's diamond rings, nothing can beat diamond in hardness), scratch will still form on the car surface. So, in the end, you get some protection against scratches, but with hydrophobic effect on the car surface too. So after rain, your car won't have a lot of water on it, and looks "shiny and clean".

Polishing is to skim off a thin layer of clear layer and sometimes, peeling off a very thin layer of paint, hence, smoothing out the surface (slightly deeper scratch will become smooth). It is always followed by a few layer of wax or coating to protect the paint surface. It is recommend to do polishing every 2-3 years only, because it will wear down the paint layer every time a polish was done.

Traditionally, the sequence goes like:
Wax once every 4 months
Polish once every 2 or 3 years, and wax on 3 times straight after polish (usually car detailing shops will wax straight after polish, number of times wax depends on package)

Now, with coating it goes like:
1st time coating RM2k
Touch up with very light polish and recoat on affected areas every 6 months (some need to pay for every touch up session)
Polish once every 3 years (depends on warranty period) to get rid of slightly deep scratch.
Reapply coating RM2k

All these are to protect against slightly deeper scratch, those deep scratch which touched the metal surface have to be resprayed to cover the metal surface to avoid rusting/corrosion. So, in the end, normally people go for respray every 5 to 6 years if they want to keep the car glitters and restore its former luster.

polishing is basically more towards "sanding" your car hence remove swirl and light scratch marks. But some product are polish + wax so I dunno but some people say it adds a layer instead.

Wax and coat is somewhat similar but coating is thicker. Wax is super thin and usually last 1-2 months only. Coating last very long but if got scratches need to repair using coating repair solution such as spray on diluted coating. These 2 don't actually prevent scratches on your car but they prevent scratches directly on your car paint work.

But since you are clueless and dowan to spend so much I can give you a suggestion:

Option A:
Option B:

the car with spoiler got number plate?
or demo unit?

I consider Mazda 2 is very sufficient for my usage.

When I am doing my decision making process, there is only Mazda 3 CBU available.

But while waiting for the car, Mazda 3 CKD was launched with Lo and Hi spec.

After test driving, my verdict on Mazda 3 CKD as follows,
Lo spec:
o Equipment wise same as Mazda 2, no cruise control, high profile tyre, no i-ActiveSense, halogen headlamp
o Advantage over Mazda 2, extra rear room leg space, 2.0L engine
o Disadvantage over Mazda 2, higher maintenance cost (tyres, service, spare parts, fuel, etc. as expected for C-segment over B-segment), no leather seats, no HUD

Hi spec:
o Equipment wise better than Mazda 2, cruise control, low profile tyre, i-ActiveSense, LED headlamp
o Price difference RM40k, those low profile tyres are noisy
o Even higher maintenance cost for tyre, spare parts (LED DRL headlamp)

Therefore, I could save that RM40k and put it into maintenance and petrol for my Mazda 2. I don't have children, and the back seats aren't that small for us asians. 
Come and think of it, I feel Bermaz did a lot of consideration for not putting LED headlamp into Mazda 2 and 3 Lo-spec, and it is a wise decision indeed. Imagine that if that LED DRL headlamp kaput, the whole unit needs to be changed, RM5k a pair!

For those who can afford RM130k Mazda 3 Hi-spec should have no problem affording RM5k spare part (wallet still bleed, but it is still within their affordability, maybe only change once every 5 years, so have to ready RM1k/year? Still, it is an affordable price for them.

Putting the LED headlamp into Mazda 2 and 3 Lo-spec, it is like asking the just-able-to-afford owners to borrow from friend, family and ah long to cover the replacement cost, and if the cost for spare parts is high, RV will be low. Hence, the easier-and-cheaper-to-maintain halogen headlamp. In Malaysia, it is still not the norm to put LED projector headlamp into B-segment. Honda City still using halogen.

The Q-85 battery cost RM740 already. Yes, it is expensive to us, but we could afford to change it once every 2 years perhaps? Which in turns translate to RM370/year for that Q-85 battery.

It happened to me once with my old Honda City, the bloody gearbox kong out just right after warranty ends. RM21k! Even worse than the LED DRL headlamp! Luckily my family members is okay to loan me the money and I slowly pay back over 5 years. 3-5 years RV for old Honda City is lower than B-segment norm then. Another example is VW's infamous DSG problem, and high cost of maintenance. RV dropped 50% in 3 years!
4WD is not suited for our road condition, it is meant for snowy and ice roads.

FC for 4WD is slightly worse than 2WD. If full-time 4WD, then the tyres will be used up earlier, and all 4 tyres have to be changed.

Our roads are wet, but not as slippery as snow. 
Could be aftermarket spoilers the owner/dealer agreed to install by 3rd party before register the car?

Where is the place?

Okay, keep posting.

i want the spoiler! >.<

hello any good sc intro? raya promo? thanks

Yeah they took it out for Asian markets just like the original armrest, i-active sense, DRL lights, airbags etc. The spoiler was on the diesel sedan show unit during the launch, but the SA told me that it won't come with our sedan variant.

The black spoiler is different, it is part of their sport kit that you can add on when you buy your car (not sure about the price). The kit will come with black spoiler, black skirtings, rims and side mirrors will be sprayed black as well.

any car not comes with brake light?
or u're talking about sedan rear fog lamp which located at bottom middle of bumper?

hello any good sc intro? raya promo? thanks

hardly will be raya promo, as the car is selling like hot cake over here, and i do believe Bermaz didn't take in many stocks from Thailand as well.... (judging by the waiting time is not short due to lotsa documentation process once the car dock the port), it's kinda interest me if Bermaz wanna CKD this Mazda 2, though there won't be a huge price difference (since currently is thai made) but they will enjoy EEV incentive and probably the saving will be reflected in the car selling price, imagine a mazda 2 full spec selling for around 80K region all inclusive. Easily kill other B seg cars.

RM2k? I recommend another shop in Setia Alam called Chemguard. They offer RM1888 + GST, Free maintenance service every 6 months for 3 years.

Not sure about the layer of coating nor hardness, but the coating is just more or less like wax, and give hydrophobic effect.

Chemguard offer 3 years warranty, every 6 months free maintenance touch up and wash car, any body panel need redo after repair is free too.

What I meant to tell is there are average coating with free touch-up maintenance service, while some good/average coating requires one to pay for every maintenance every 6 months/1 year interval, else void warranty. Some even need you to wash at their own shop only, every 1 or max 2 weeks interval, if not void warranty. If I am not mistaken G'zox at Sunway was like that before, now don't know.

So it is better to do survey and ask carefully.
Haha! Maybe at Ipoh have something like coating, else, don't bother about it and do the "wax and polish" style. Coating isn't any good in protecting paint, it still scratch if someone butt is too big to fit the gaps between your car and theirs in parking lot. And the open door whacking will still make a dent on the paint.

Yes, but there is a limitation to the protection given. There will be scratches, just an additional layer add to it. E.g. if the scratch is 10 micron deep, and your clear layer above the paint is 5 micron thick, 5 - 10 = -5, it will eats additional 5 micron into the paint. But with another layer of coating on top of the clear layer, say 6 micron, so the scratch is 6 - 10 = -4, it eats 4 micron into the clear layer, sparing the paint layer. That's all...

The harder the coating (hardness level), the harder the scratching material and more force needs to scratch through it. With enough force, it will still form scratch. It is not 100% scratch resistance, it offer extra layer protection, but not total protection from scratch. Example, the sharp tip of a key or diamond ring will still scratch through the coating, just the coating absorbs some of the scratching force and won't eats through it.

Want 99% protection from scratch, get a diamond layer. 

Point is, after a while, you also need a respray. Nothing saves your car from dents. Use your 2k for a respray. Coatings should be reserved for cars 200k and above. Makes more sense.

No discounts but you can ask for personal discount (for dealer) because their margin is higher. I got rm500 + free gifts
