I read through your comments and thanks for educating. It was very useful. My concern is stone chip and particularly im worried about the front bumper and hood. what would you suggest? coating or ppf. And also budget is my concern 

Cna u tell more on PPF harder to take care than coating? Why is that

Thanks for the information. Looks like wash and wax regularly would be the way to go.

Any car wash you like. I prefer to wash it myself without using high pressure wash as I afraid of peeling off the PPF adhesive on the edge.

Bro,

I have spent $$$ for the past decades to do PPF, Coating etc etc.

My advice: do not waste your hard earned $$$ away on these bs. None is worth the money spent.

Just wash your car, apply some wax and coating yourself periodically is the only way to do.

Do not trust anyone telling you after PPS / Coating = no need to wash car, just hose it down, it is all bs.

You must well keep the $$$ and do respray of your car every few years = looks 100% new again.

I suppose very few people will repaint their old cars just to make it look new again although the original paint do not have any major scratches and still look good. People will only respray the car usually only at the part where it is damaged due to accident, or there are major scratches or dents which will require repair and respray.

When the car is already old, say more than 5 years, the interest to spend money on the car to keep its outlook appearance at tip top condition is less already. It's only when it is new up to about 2 years old, then only you try to keep it looking as good as possible since it's new. Everything new you will treasure more, and when it's old it will lose its appeal so you don't pay so much attention to it anymore. With older cars, most people will just focus on the maintenance, less on the appearance since it's old already. Just try to keep it scratch free or accident free is good enough by practicing good parking and driving habits.

Also, most people would have wanted to sell their cars when it's approaching 10 years, and if the original paint is still in good condition it makes little sense to respray the cars. Some even sold their cars earlier in 5 years or earlier. In my mind as long as there are no major scratches on the car, that's good enough.
