I picked up a bottle of this cleaner after buying my GT1 and it works well when getting the oil and dirt marks off as much as the basic cleaner. Was checking to see if anyone else likes it as well as the other products that Motiv has (Polish and Scuff)?
However, I did noticed when I bought the Track 505C that there was something in the box stating that gel cleaners are not recommended because it might damaged the coverstock. Don't know if that's true since the Power Gel is USBC approved and have used it on my 505C several times.
