1 of 5 Does not work March 3, 2020
Reviewer: David from Jones  
made the mistake thinking this product would solve my dull quartz.
Applied as per instructions, it looked good for a day or so.

Made the quartz sticky, harder to clean and just came off in a few days.
Seems like and smells like a sealer, which Caesarstone has informed me that can not and should not be used.

2 of 5 Wipes off when wet December 18, 2018
Reviewer: Chris Modrzynski from Easton, Pa  
After applying 3 coats per instructions, the countertops looked great. Unfortunately, everything came off with the first wipe/cleaning with water.  Back to same dull look.  So if you don’t want to sue your counters than this does the trick.  Otherwise not so much.  I’ve seen similar reviews online, as well (after I purchased).
