How much did it cost you for your rotary buffer? Those things seems expensive.

And by DIY ourselves, it is easy to screw up the paint job while polishing?

Almost twice a month I wax and apply spray wax without fail. I am using Meguiars  ultimate synthetic wax and I park my car under the shade without fail.

Still no idea why the body suffers color change.

I jenis oldschool, semua pakai tangan 

Pakai tangan its actually very gentle.
So far after 1 year of regular cleaning and care, my paint is still like new. But got some mofos dinged my car before... so got minor scratch one in front and one at the back la.

I read up quite a bit on autogeek and also test it out by myself.

But I cakap betul la, can't rush these things. Slowly do nvm, cuz what we want is the results.
Put in the effort required, give it the time it needs to cure, then it'll give you the results you want. 

Oh guys, I need a super water sucking cloth to wipe dry my car.

I'm currently using synthetic chamois which is leaving water streaks behind.

Any idea where to get cloth like the shamwow advertisement?

Not the first time i'm hearing this bubble wash/bubble wax causing issues for car owners. If improper shampoo used, will cause spots/etching.
Mind sharing your car wash routine and material used?

i just bought a car from used car dealer 2 months ago, initially the paint condition looks acceptable, then day-by-day more scratches surfacing and the paint begin to fade (grayish appearing). also the windscreen begins to accumulating water-spot from no water spot to heavy water-spot. I wash my car almost every week myself. owning few cars before and never had those issues occurring so fast in short period. so ytd i send my car for polishing and waxing.
i believe the car wash center which using bubble wash detergent cleans all dirts off. i got shocked of the paint condition after car wash.
this area become so horrible after bubble wash:


boot condition also very poor:


after the polish and wax the condition looks better, not 100% but acceptable. my question is, how come my paint condition can deteriorate so fast in 2 months? when the car was collected, the paint doesn't looks so bad...

About 1 year plus. Almost twice a month I wax myself with Meguiars ultimate wax and apply spray wax after each car wash.

Worst come to worst, I would just repaint the whole car few years later or once the condition get worst since White solid paint is cheap.

Meguiars White Wax. Thats your go to for a white car. What douglas_tong suggested was correct too.
Trust me (white car owner here), I've done the 3 steps and it still comes back yellow.

White wax, peace of mind  Polish + Wax. If you want extra wet look, Ultimate Compound + White Wax.

My suspicion is the dealer masked the imperfections with a thick coat of wax. That's why as u wash and strip away the wax, the imperfections appear. If your swirl lines are circular, then its polishing fault, if your lines are generally straight, then its washing fault.

Also a strong possibility is your clearcoat is VERY soft, most likely local clearcoat. Soft clearcoats scratch and swirl very easily, and generally recommended to do coating if u dont want to respray. To know for sure, since u just polished and waxed again, continue your regular routine again and see if it comes back.

For your windshield, not too sure, but do u park this car outside often under the sun often? Older car windshield gets baked water spots faster generally. See if u can get someone to polish your windshield one round, then monitor the situation from there.

When I was running my shop previously, my biz partner has a white Myvi that has also turned yellow from wear and tear. After polishing he applied coating for his car and it managed to maintain the whiteness of the car for a much longer period of time. So, if you prefer to keep your white car white for a longer period of time without constantly repolishing, I would suggest applying coating instead.

thanks for the tip. Do you send your car to professionals or diy yourself? Any recommendation?

Any sealant to recommend?

Any sealant to recommend?

when i bought mine... the fake ones were not around 

Sorry, I'm not very good with sealants, had a bad experience with sealants as they are very hard to buff when dry. I would generally go back to wax, or if I have coating available, do coating myself.

from my resesarch
wolfgang deep gloss paint sealant v3 is da best sealant
