just to add on, this sierra glow is crap. one of my car is coated by sierra glow and this mr. chong said no need to wax/polish, bla bla bla. just wash as normal. so i did what he asked. couple of months down the road, the coating was completely gone!. so i bring my car for him to inspect and guess what he said? oh, that's because you sent your car to polish/wax hence there is some swirl mark (which i never did, why would i wanna pay for a coating and then send my car to polish and wax?). he said he can re-coat back the car but with additional RM450 to remove the swirl mark and apply another layer of coating. i told him no and walk away. he just laughed. yeah, mr. chong can sound like a good guy / knowledgeable but deep down he's just a greedy businessman that doesn't keep his words. 5 years warranty is a lie.
