I used it and reviewed it in the link below. I write very honest reviews. Interior detailing for the most part is pretty mundane and boring unless it's an "extreme" interior detail on something older. this review was using the product on a brand new Mercedes-Benz.
Review: GTechniq C6 Matte Dash AB Antibacterial by Mike Phillips
The 3 P's = Perfect Product Placement
By misting the product onto a clean microfiber towel INSTEAD of misting the product onto the dash I get perfect product placement and avoid getting overspray product onto the inside of the glass and we all know what a paint the inside of the front windshield is to clean.
My guess would be --> maybe somewhat.
Think about it... if you're rubbing a cleaner over another microscopic film of product will rubbing the cleaner ADD MORE of the previously applied product?
If you answer "no" then ask yourself,
What is the opposite of the word ADD
One thing for sure, Gtechniq makes GREAT products and you can trust the brand name to mean high quality.
