This green pad is designed for applying a final or finishing polish to remove light swirls, paint defects and for gloss restoration. This pad is also recommended for applying one-step, cleaner/sealants like Klasse All-In-One. It is a high strength foam with 60 pores per sq. inch yet is surprisingly soft and forgiving. It is designed to be used with an orbital polisher (like the Porter Cable 7424XP) but can be used with a rotary polisher if the speed is kept around 1000 rpm.
