i had my polishing done by them last yr. Have not tried out any other pro polishing so don't know how it compares with other pro polishing. i was actually deciding between Zaino and Glare the other time and ended up with Glare..
Depending on what is your objective of the polishing : eg to make the car glossy shine, have one protective layer so you never need to worry abt paint oxidation.. need to set correct expectation..
if its for the former, black or darker col cars tend to appear more shinny than other cols. anyway, for dark col cars, any off-the-shelf polish/wax will achieve that level of shine as well. my neighbour has a black col Subaru and he polishes himself. It looks so much more shinny than mine.
if its for the paint protection, there is this 18mths warranty that you can go back to them. the point abt 'no wax, no polishing required and only need washing and road grimes floats away' may be kind of overstatement lah. Even with weekly washing myself, few mths after my pro polishing, noted some stubborn stains appearing on the car surface. Went back to them to have them and 'persuaded' them to remove them..
