While 180 mm range pads may be physically compatible with some rotary backplates due to the universal hook and loop backing, they are primarily designed for use with dual action polishers with a 21 mm throw.

Using these pads on a rotary polishing machine is not recommended, as the larger diameter with a mismatched backplate and intended machine action can affect balance, handling and overall performance; making the machine harder to control and reducing consistency in cut and finish.

For best results, pads should be matched to the correct machine type and size to maintain stability, control and finishing quality.

Farécla does not currently offer a 21 mm throw Dual Action Polishing Machine.

NOTE: Due to an administrative error, some early “new look” packaging (see “G Mop Applicator Range – Packaging Update”) for GMC760 incorrectly states Rotary compatibility. Artwork has been updated, and future production runs will carry the revised information

Although similar in appearance, GMC660 (the WHITE G Mop Super High Cut Pad) and GMC650 (the RED Pad) differ in use:

When using a Rotary Polishing Machine, Farécla advises using the pad at a slight angle to the surface.
GMC660 is designed to be used flat.
For that reason, Farécla does NOT recommend using GMC660 with rotary polishing machines.

A skilled operator may still achieve acceptable results when using GMC660 on a rotary machine if correct polishing practices are followed. However, performance is likely to fall below expectations in both cut and finish, and additional spurring may be required to maintain.

GMC650 is optimised for rotary polishing. It performs more consistently when used at a slight angle and provides better control in this application compared to GMC660.

Farécla offers two types of G Mop Super High Cut Pad(s):

The RED Pad
150 mm Range: GMC650 (78072700153) 
Introduced alongside G360 Super Fast Compound, this pad is recommended for use with ROTARY polishing processes.

The WHITE Pad
150 mm Range: GMC660 (66254427056)
180 mm Range: GMC760 (66254427057)
Introduced in 2026, this pad is recommended for use with DUAL ACTION polishing processes.

Both pads are designed for use with G360 Super Fast Compound and will remove P1500 or finer sanding scratches when used as part of the correct process.

While similar in appearance, subtle differences in dimensions, foam structure and the fibres of the polishing face mean they behave differently in use. As a result, each pad requires a specific handling approach for optimal control and to avoid introducing additional surface defects.

For best performance, Farécla recommends:
GMC650 – Rotary use ONLY
GMC660 & GMC760 – Dual Action use ONLY

Further guidance is available in the related FAQs: 

• Can GMC650 be used with a DUAL ACTION Polishing Machine?
• Can GMC660 be used with a ROTARY Polishing Machine?

NOTE: Due to an administrative error, some early “new look” packaging (see “G Mop Applicator Range – Packaging Update”) for GMC650 and GMC660 incorrectly suggest cross-use between rotary and dual action polishing machines.

No. Polishing should refine the surface, not compensate for unresolved nibs or texture issues. Proper denibbing and preparation are essential.

Halos are typically caused by over-refining the repaired area while failing to blend outward into surrounding paint, creating a mismatch in gloss or texture.

Because clearcoat thickness is non-uniform, working areas are confined, and heat builds rapidly, leaving less tolerance for aggressive correction or prolonged polishing.

Spot repair polishing is the controlled refinement of a localised paint repair to remove defects, equalise texture and gloss, and blend new paint seamlessly into surrounding OEM finishes.

The right approach depends on the surface, the defect, and the result required:

• One-step efficiency - use a compound with both high cut and gloss (e.g. G360 Super Fast Compound) for maximum speed and reduced stages.
• Two-stage flexibility - use a compound like G3 Premium with different pads (yellow foam for cut, black foam for gloss) for a tailored result.
• Multi-step systems - lower-priced compounds generally cut slower and deliver less gloss, so a second finishing product is required.

Pads make a significant difference to how a compound performs. By pairing the same compound with different pads, you can push the result towards faster defect removal or higher gloss:

• Super High Cut Pad – increase cutting power, ideal for coarse hand-sanded P1500 marks.
• Compounding Foams (Yellow) – balance cut and finish, often used after DA sanding.
• Finishing Foams (Black) – refine gloss by reducing haze and micro-scratches.

The pad acts as the compound’s partner - it determines how aggressively the abrasives work against the surface and how fine the finish will appear. This makes pad choice just as important as compound choice in achieving the right balance of cut and gloss.

Traditionally, polishing has involved a balance - compounds designed for fast cutting remove heavy defects quickly but may leave surface haze or micro-scratches that reduce gloss. Compounds designed for finishing give a clear, mirror-like result but lack the abrasive strength to tackle deeper marks.

This is why multi-stage processes are common - a cutting stage to remove defects, followed by a finishing stage to refine gloss.

However, the pad also plays a major role in this trade-off.

• Using a high cut pad increases the cutting power of the same compound, helping with coarse sanding marks.
• Switching to a softer finishing pad with the very same compound allows it to refine the surface further and improve gloss.
• Mid-range compounding foams balance the two, giving cut with good clarity.

So, while the compound formula sets the baseline, the choice of pad and machine can push performance more towards cut or gloss depending on the job.

Gloss is the clarity, depth and reflectivity of a surface after polishing. In simple terms, it is how "mirror-like" the finish appears - free from haze, micro-scratches and swirl marks. A high gloss finish reflects light sharply and shows clear, undistorted images.

How gloss is measured

• Gloss Units (GU): Measured using a glossmeter, which shines light onto the surface at a fixed angle (commonly 20°, 60° or 85°) and records how much is reflected back.
• Distinctness of Image (DOI): Goes further than gloss by measuring how sharp or blurred a reflection appears — important for high-end finishes.
• Haze: Measures the “milky” or dull appearance caused by fine surface micro-scratches that scatter light.

A surface can have “high gloss” readings on a glossmeter but still look poor to the eye if haze or low DOI is present.

In polishing practice

• Compounds with stronger finishing ability reduce haze and improve DOI as well as gloss.
• Pad and machine choice influence gloss level — finishing foams (black) are designed to maximise clarity.
• High-gloss results matter in automotive, marine and industrial applications, where finish quality is a visible marker of workmanship.

Cut refers to how quickly and effectively a compound can remove surface defects such as sanding marks, scratches or oxidation. A high cut compound uses engineered abrasive particles to abrade the surface more aggressively, removing deeper marks in less time.

• Faster cut = quicker defect removal
• Higher cut compounds are often used as the first step in a polishing process
• The level of cut achieved depends on both the compound formula and the pad or machine used
