Heavy Cutting Directional Scratches: Avoid an Inspection Blind Spot
Scratches can look dramatically different when the inspection light moves.
Heavy Cut for a Few Deep Scratches Among Light Swirls
A panel with widespread light swirls and a few deep isolated scratches does not necessarily need the same heavy-cut treatment everywhere.
Heavy Cut on Concave Panels: Check the Pad Contact Footprint
On a concave panel, a pad can bridge the recess while its edges carry much of the contact.
Heavy Cut After Sanding: Diagnose One Remaining Coarse Scratch
One coarse line remaining after compounding a sanded area may belong to an earlier sanding stage.
Heavy Cutting Textured Clear Coat Without Flattening the Appearance
Heavy cutting can improve scratches while also changing how existing clear-coat texture looks.
Heavy Cut on a Panel with Unknown Previous Corrections
An attractive used car may have been machine-polished several times before it reaches the workshop.
Heavy Cutting Across a Repaint Boundary: Use Separate Acceptance Zones
A repainted door and its original adjacent panel may respond differently to the same heavy-cut combination.
Heavy Cut Compound Starts Strong Then Slows: Check Pad Loading
A heavy-cut system that works quickly on the first section and becomes sluggish later may have a pad-condition problem.
Heavy Cut and Intermittent Pad Rotation: Diagnose Uneven Correction
On a free-spinning dual-action polisher, rotation can become intermittent when contact, pressure or panel shape changes.
Heavy Cut with a New Wool Pad: Separate Loose Fibres from Compound Dust
Loose fibres from a new wool pad and dust from a drying compound can look similar around a heavy-cut work area.
Heavy Cutting Thin Painted Strips: When a Machine Pass Is the Wrong Choice
A narrow painted strip can be smaller than the controlled working footprint of the available machine and pad.
Heavy Cut on a Tall Vertical Panel: Control Reach and Pad Angle
Heavy cutting a tall vertical panel becomes less consistent when the operator reaches beyond a comfortable working position.
