i have install coating the sierra glow since 2012 new car during that time

after that..i am giving up. why? i am not satisfied

after a month or two..my pearl white is getting a lot of dust and dirt.

is all bullshit talk.it say it going use plain water wash can be removed.

second that..it make no different when i go do outside polish or wax.

i don't see any big different, why should i need pay more ...if i can going for wax or polish Rm 100 every 3-6 months outside.
my review is..if you keep maintenance washing every week. you not need go do coating.
