3M 05737 Perfect-It Foam Compounding Pad 8 in | P1200 Sand Scratch Refinishing Pad for Hookit Backup

3M 05737 Perfect-It Foam Compounding Pad 8 in — P1200 Sand Scratch Refinishing Pad for 3M Hookit Backup Pad & 3M Compounds

The 3M Perfect-It Foam Compounding Pad is the highest-performing foam compounding pad in the 3M Perfect-It Paint Finishing System, designed to refine P1200 or finer sand scratches on gel coat and automotive paint surfaces during machine compounding. The inset pad design and foam construction hold compound on the pad surface, preventing sling during machine operation for faster and cleaner results. Compatible with the 3M Hookit and Quick Connect backup pad attachment systems — for use with 3M Hookit Backup Pad 05717 or 05718 (sold separately). The 8 in. diameter is the standard size for DA and rotary polisher compounding work on flat and moderately curved hull and deck surfaces.

Compatible Backup Pads & Compounds

The 3M Perfect-It Foam Compounding Pad (05737) requires a compatible 3M Hookit Backup Pad to mount on a DA or rotary polisher — the backup pad is not included and must be purchased separately. Compatible backup pads:

• 3M Hookit Backup Pad 05717 — standard Hookit backup pad for DA polishers
• 3M Hookit Backup Pad 05718 — alternative Hookit backup pad; verify diameter compatibility with your polisher before ordering

For compound product compatibility, this pad is designed for use with 3M compounds in the Perfect-It system, including 3M Perfect-It Heavy Cutting Compound and 3M Perfect-It Medium Cutting Compound + Wax. After compounding with this pad, step to a finishing pad and finishing polish (such as 3M Finesse-It II, 3M-05928, or 3M Perfect-It EX Ultrafine, 3M-06069) to refine the surface to final gloss before waxing or coating.

Application Notes

• Mount the foam compounding pad on a compatible 3M Hookit Backup Pad (05717 or 05718) before attaching to the DA or rotary polisher — the backup pad is sold separately
• Prime the pad before use — apply a small amount of compound to the pad face and spread at low speed before increasing to working speed
• Apply compound to the pad or directly to the surface in small amounts; work in overlapping passes at medium machine speed with light to moderate pressure
• The inset foam design holds compound on the pad face during machine operation — this reduces compound sling and extends working time per application
• Designed to refine P1200 or finer sand scratches — for coarser scratches (P800 or coarser), use a cutting compound and appropriate pad before stepping to this pad
• Clean the pad after each use — compound residue left in the foam will dry and harden, reducing pad performance and contaminating subsequent compound applications
• Inspect the pad before each use for tears, glazing, or hardened compound residue; replace if the foam is no longer soft and uniform

Frequently Asked Questions

Q: What is a foam compounding pad used for, and how is it different from a finishing pad?
A: A foam compounding pad is a more aggressive pad designed for use with cutting compounds — it removes heavier surface defects, sand scratches (P1200 and finer), oxidation, and compound marks more aggressively than a finishing pad. A finishing pad is softer and less aggressive, designed for use with finer finishing polishes (like 3M Finesse-It II or Perfect-It EX) to refine the surface after compounding to a final high-gloss result. In a multi-step system, the compounding pad comes first, followed by a finishing pad as the final abrasive step before wax or coating.

Q: Do I need a backup pad to use this foam pad?
A: Yes — the 3M Perfect-It Foam Compounding Pad requires a compatible 3M Hookit Backup Pad (05717 or 05718) to mount on a DA or rotary polisher. The backup pad is sold separately and is not included with the foam pad. Make sure the backup pad diameter matches the foam pad diameter and is compatible with your specific polisher before ordering.

Q: What does P1200 or finer mean, and how do I know if my surface qualifies?
A: P1200 refers to the grit level of sandpaper used in wet sanding — P1200 is a fine wet-sand grit commonly used in final sanding stages before machine polishing. “P1200 or finer” means this pad is designed to remove the scratch haze left by P1200, P1500, P2000, or finer wet sanding. For surfaces sanded with coarser grits (P800 or below), use a more aggressive cutting compound and pad first, then step to this pad for the refining stage.

Q: What compounds should I use with this pad?
A: This pad is designed for use with 3M compounds in the Perfect-It system — specifically 3M Perfect-It Heavy Cutting Compound and 3M Perfect-It Medium Cutting Compound + Wax. Do not use finishing polishes (like Perfect-It EX Ultrafine or Finesse-It II) with a compounding pad — the pad aggressiveness will cause the finishing polish to work less effectively and may mar the surface.

Q: How do I clean and maintain this foam pad to extend its life?
A: Clean the pad after every use by rinsing with water and gently working compound residue out of the foam by hand or with a pad cleaning brush. Allow to dry fully before storage. Do not leave compound residue in the pad — dried compound hardens the foam, reduces cut, and can contaminate future applications. Store flat or face-up to prevent the foam from deforming. Replace when the foam becomes glazed, hardened, or structurally damaged.
