Product Description

The MaxShine Pro Series Dual Action Backing Plates are professional-grade replacement backing pads engineered specifically for high-speed Dual Action (DA) polishers. Constructed from highly durable, flexible polyurethane, these plates are designed to withstand the intense mechanical power and colossal orbital throw generated by modern long-throw polishing machines, such as the MaxShine M15 Pro and M21 Pro.

In professional detailing and collision repair environments, managing heat during the compounding and polishing phases is critical to preventing pad failure and clear coat burn-through. The MaxShine backing plates feature an advanced heat-resistive design with integrated cooling channels that dissipate extreme friction temperatures. Rated to safely support operational speeds up to 12,000 Orbits Per Minute (OPM), these plates ensure smooth, balanced pad rotation and consistent cutting power across curved automotive body panels.

Key Features

• Heat-Resistive Design: Smart heat management structure channels airflow through the plate, rapidly dissipating friction heat to extend the life of foam and microfiber polishing pads.

• Flexible Polyurethane Construction: High-quality, flexible material easily contours to complex body lines and curved panels, ensuring even compounding pressure without stalling the machine.

• High-Speed Capacity: Structurally reinforced to handle aggressive paint correction workflows, safely supporting machine speeds of up to 12,000 OPM.

• Universal 5/16" Thread: Features an industry-standard 5/16"-24 threaded connection, making it compatible with a wide range of professional DA polishers.

• Dual Size Options: Available in both 5-inch (for tight contours and M15 polishers) and 6-inch (for broad, flat panels and M21 polishers) configurations.

Ideal For

• Auto Detailing Professionals: Executing heavy paint correction, compounding, and final polishing stages with large-throw DA polishers.

• Collision Repair Facilities: Blending fresh clear coat and removing sanding marks efficiently prior to returning vehicles to customers.

• Machine Upgrades: Replacing worn, unbalanced, or degraded factory backing plates to restore smooth, vibration-free polisher operation.

Common Questions

Q: What polishers are these backing plates compatible with?
A: These backing plates feature a standard 5/16" diameter thread, making them fully compatible with the MaxShine M15 Pro and M21 Pro, as well as most other industry-standard Dual Action (DA) polishers that utilize a 5/16" mounting spindle.

Q: Should I choose the 5-inch or 6-inch backing plate?
A: The 5-inch plate is ideal for navigating complex curves, bumpers, and standard 15mm throw machines. The 6-inch plate maximizes surface area coverage for large, flat panels like hoods and roofs, typically paired with 21mm long-throw polishers. Always ensure you pair the plate with the appropriately sized polishing pad (e.g., a 6-inch pad for a 6-inch plate).

Q: Why is polyurethane better than standard hard plastic backing plates?
A: Polyurethane offers superior flexibility, allowing the polishing pad to conform smoothly to the curvature of the vehicle's bodywork. This prevents the edge of the backing plate from digging into the paint and provides a much smoother, balanced operating experience.
