read up on some of the downsides before you proceed. unless your vehicle is a classic or vintage for collection, or you plan to keep the new vehicle through the decades as a keepsake, beware of the downsides. moreover the harsher tropical environment, pollution, and higher temps in thailand may tip the balance in consideration. all my vehicles except a z350 maintain very good shine after 10 years without nano-glass polymer coating. they are still in their original paint and clear coat. the environment is cooler but the engines are burning hotter under the hood as they age and go through a decade of wear and tear all over.
this section is from a ceramic coating expert....lots of them here as one of the classic and vintage car museums is not too far away (have a thread dedicated to that in the serious zone folder).

What are Some Downsides?
When considering one of these coatings, the pros and cons for a consumer may be different than those of a specialized detailer.
Before you can even apply the coating, the surface has to be 100% free of surface blemishes, which applies to even brand new vehicles. A multi-stage paint correction involves washing the car, claying, buffing, and keeping it pristine while applying the coating. That last step is particularly difficult for anyone who isn’t working in a clean indoor facility.
Nearly all of these coatings use extremely harsh chemicals that when you open the bottle, smell like a nice sampling of jet fuel. After speaking with many detailers who specialize in applying many of these coatings, they mention how they need to take frequent breaks to refrain from going light-headed. These harsh chemicals contain high levels of VOC’s.
Furthermore, when you have a coating that is unlikely to lose it’s bond with the paint, when a paint correction is needed (and believe me, it will be), you lose the coating and all the money that went into it as well.
And lastly, they’re quite expensive. You’re talking about a potential four figure number to get a detailer to do all this work for you.
also, to add, your car body's metal will expand and contract with heat and cold. after coating, there's no guarantee that badly applied coating may crack as the material is not as flexible as metal with metallic-flake paint and resin-like clear coat.
