Never tried the Griots, but have used 845 for years. If the instructions say THIN, heed this.
A lot of posts on here saying they have problems working with/removing these products are, in my opinion, NOT applying it thin enough.
When the products say thin, it means BARELY apply the products to the paint.
This is how the products should be applied, and how they work the best.
Some people (IMO) cannot wrap their heads around the word "THIN".
For example: The bottle of 845 I purchased in 2013 has been applied to my full-sized Ram truck and my wife's Jeep Wrangler 7 times each.
The bottle still contains about 30% product.
