I see, will the white turns yellowish in time too even with regular detailing?
Hey! Nice see-ing you here too!
Noted on the caveats, maybe i try apply on a small section and see how is the effect first. Any brands can recommend me to look into for starter?

Getting the car soon wanna preserve the white as long as possible..

with regular detailing, definitely not.
the clear coat may thin out if you do a lot of polishing/compounding (which you shouldn't if the car is well maintained since day 1 or a major detailing session)
coating wise i am not familiar since i am still into old school (analog?

) wax/sealants.
my main LSP (last step protection) are DodoJuice Blue Velvet, Meguiar ULW (ultimate liquid wax), and Sonax Profiline HW 02-04 (hw = hard wax)
then supported by Sonax BSD (brilliant shine detailer), Meguiar UQD (ultimate quik detailer), Meguiar UQW (ultimate quik wax)
or maintenance with Turtlewax cheapo Zip Wash and Wax or Turtlewax ICE wash and wax if i am not plain washing + spray LSP with Meguiar Gold Class car wash (not wash and wax)
looking forward to trying out the new hybrid/ceramic/graphene/sio2 etc etc new spray sealants when my existing products deplete

personally, no need bother 1 small section, straight whack whole car and as the protection/reapplication and product finish , you try something else.
detailing products typically quite competitive so if you're on reputable brands, and especially home consumer lineup, it's VERY hard to go wrong.
