I'm still interested but is there writeup on PPS that I could have a quick read before I decide?

I got ur point.. I already did meguiar's sealant at Imola Autospa jalan ampang.. They are very professional and using only meguiars product.. They not mix with other brands.. But the sealant is only can last for 3-4months the max.. Then no promises at all for the "shine look" for the next 5 years.. If u want to really maintain u have to do it twice a year and 1 time polishing a year.. How much it will be?? Quite expensive.. It is good if u want to do it ur self.. But do u really know how is the proper way to do it?? Becareful with the machine or hand if u want to do it urself because the swirl will get worst if u do it in a wrong way.. Especially on black car.. So the paint protection will ensure us the shine look for the next 5years.. Plus if we use pps we still can send to polish the car back.. Just my 2cents..
