Its called (liquid clay bar ice )made by turtle wax its blue in colour and applied to the car wet then rubbed in and then washed off ,ive never heard of it over here but seems to do the job and is very easy to work with,i had asked my dad to get the normal clay bar but this is what he got and it only cost $14 for 475ml bottle,hope this helps you detailing guys out there.
