The Perfect Balance for Finishing Auto Body PanelsThe 3M™ Ultrafine Foam Polishing Pad is engineered for the perfect balance: it holds up during the final polishing process. Properly used with 3M™ Perfect-It™ EX Ultrafine Machine Polish, it delivers a refined cut to eliminate swirl marks, haze and holograms without compromising the high gloss of the panel. Its foam construction and specially designed face holds polish and prevents slinging during critical final paint finishing.Single-Sided Foam Pads and Our Hookit™ Attachment SystemThe Hookit™ attachment system has a hook-and-loop feature which makes disc attachment, removal, and re-attachment of 3M™ Ultrafine Foam Polishing Pads clean and easy. It also facilitates use and re-use of the disc for maximum product life. Hookit™ discs have a brushed nylon loop backing of the type most commonly used in everyday hook-and-loop applications. A range of Hookit™ disc backup pads features hooks which grip the brushed nylon loop backing. It's simple: just attach the disc and start sanding. The disc removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed abrasives may become contaminated by dust, dirt or debris.
