OK...I purchased the Klasse Twins (All-In-One, Sealant Glaze) from Detailers Paradise and haven't attempted using either product yet. Are both these products safe for the Starshield? After reading the thread(s) regarding Maplecrest and others experiencing scratches, swirls, clouding, etc.

need to know the "best" method of using the Klasse products.
Any advice is appreciated.
