The Sonus DAS Blue Foam Pad is to be used on clear coats for final gloss polishing and pre-wax cleaning. When used with a pre-wax cleaner or fine polish, such as Sonüs Paintwork Cleanser, it will improve overall gloss, but it will not remove paint defects.
This pad works great with Sonus Paintwork Cleanser, Klasse All-In-One and P21S Paintwork Cleanser.
Use the Sonus DAS Blue Foam Pad to apply liquid waxes and sealants, too. The silky-smooth texture of the blue foam applies a thin, even coating of wax or sealant protection.
You shouldn't have any "cut" from the blue pad.
