Product Information
Full details
The 3M Perfect-It Extra Fine Plus Compound (80349) is designed for professional automotive detailers and body shop technicians who require a high-performance finishing solution for modern, scratch-resistant clear coats. This compound excels at removing fine sanding scratches and persistent swirl marks, leaving behind a superior high-gloss finish. While it offers industry-leading correction capabilities, users should note that it is specifically formulated for fine-finishing stages and may require a heavier cut compound if dealing with deep or heavy paint defects.

FAQs
Is this product safe for all types of clear coats?
Yes, it is specially formulated for modern, scratch-resistant clear coats, but it works safely on most standard automotive clear coat systems.
Do I need to follow this with a polish?
While this compound provides a high-gloss finish, using a final finishing polish or glaze is recommended if you are looking for the absolute highest level of clarity and depth.
Can I apply this by hand?
It is designed primarily for machine application (rotary or orbital) to achieve the friction needed for the abrasives to work correctly. Hand application will not yield professional results.
How do I know which pad to use?
3M recommends using this with their corresponding foam compounding pads to ensure the best balance between cutting power and surface refinement.
What is the best way to clean the pads after use?
Use a dedicated pad cleaning tool or warm water with mild soap. Ensure the pad is completely dry before using it again.
Troubleshooting
Compound drying out too quickly on the paint surface
Reduce the working area size or add a light mist of water to the pad to increase lubrication.
Difficulty removing dried residue
Wipe away while the surface is still slightly warm or use a clean microfiber towel with a light touch of detailing spray.
Holograms remaining after polishing
Check your machine speed and technique; ensure you are not applying excessive pressure and are properly breaking down the compound.

Setup, Compatibility & Care
To ensure optimal performance, use this compound with an appropriately matched 3M buffing pad. It is recommended to shake the container well before use to ensure the formula is properly mixed. When applying to the pad, avoid overloading; a small amount typically covers a 2-foot by 2-foot area.
Always ensure the paint surface is cool to the touch and out of direct sunlight before beginning the process. After use, clean your buffing pads immediately with a dedicated pad cleaner or warm soapy water to prevent the residue from hardening, which can cause marring during your next use. Store the bottle in a cool, dry place and ensure the cap is tightly sealed to prevent evaporation.
