FAQ
Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?
Abrasives usually clog because removed dust, paint residue, or filler particles are not cleared away in time and accumulate on the abrasive surface. Once this builds up, cutting drops off and the abrasive is more likely to run hot, fray, or shed grit.
You may also want to compare this with In automotive refinishing, how should you choose between dry sanding and wet sanding? and Why are film abrasives more stable and less likely to shed grit or deform in continuous sanding?.
Common causes:
-
Excessive pressure increases surface heat and makes dust stick more easily.
-
The selected grit range is not suitable and the jump between steps is too large.
-
Dust extraction is missing or not efficient enough.
-
Softer or more resin-rich materials are naturally more likely to load the abrasive.
How to reduce clogging:
-
Let the abrasive cut instead of forcing it with heavy pressure.
-
Choose grit sizes according to each process step and avoid large jumps.
-
In dusty conditions, prioritize more anti-loading backings and structures, and use dust extraction whenever possible.
-
Replace the abrasive once cutting slows down noticeably instead of continuing until it is completely clogged.

What abrasive grit sequence is more reliable for automotive refinishing?
There is no single fixed sanding sequence for every repair job, but a safe rule is to move from coarse to fine in gradual steps.
You may also want to compare this with In automotive refinishing, how should you choose between dry sanding and wet sanding? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
A common workflow is:
-
P80-P120: for initial body filler shaping, correcting obvious defects, or removing old coatings quickly.
-
P150-P240: for intermediate sanding to remove deeper scratches left by the previous step.
-
P320-P500: for surface preparation before primer or surfacer.
-
P800-P1500: for fine sanding before topcoat, blending areas, or higher-finish refinement.
-
Above P1500: better suited to fine wet sanding, pre-polish preparation, or correcting minor defects on high-gloss surfaces.
Practical tip:
Avoid jumping directly from a very coarse grit to a very fine grit. Deep scratches from the previous step can remain and cause rework. A step-by-step progression is usually more stable.

Is sanding sponge better for curved surfaces?
A sanding sponge is usually better for curved surfaces than regular sandpaper because its flexible foam backing can conform to contours, edges, and uneven shapes more easily. This helps distribute pressure more evenly and reduces the risk of deep sanding marks.
For automotive surface repair, sanding sponges are especially useful on curved car panels, bumpers, body lines, primer surfaces, and small repair areas. They are suitable for both fine sanding and surface preparation before painting or polishing.
For best results, choose the right grit for your application and avoid pressing too hard. Let the abrasive surface do the work while keeping steady, even movement across the curved area.
