Mirka 23-573-220 Bulldog Gold PSA Autokut Roll is a PSA sanding roll built for finishing and material removal work where you need consistent cut, long roll length, and cleaner sanding performance. This is a sanding roll designed for surface preparation and finish sanding. Model Number: 23-573-220.

What matters here is the combination of a 220 grit abrasive and Mirka's Gold series construction. That puts this roll in a useful spot for finer prep work, blending, and smoothing rather than aggressive stripping. If you are working through sanding steps and want a more refined scratch pattern before coating, this grit range makes sense.

The abrasive material is aluminum oxide, which is a proven choice for sanding because it cuts quickly and holds up well over time. In practical use, that means the roll keeps working instead of going dull right away, especially when you are tearing off repeated lengths for hand sanding blocks or other finishing tasks.

Mirka also calls out a semi-open coat and a special stearate treatment. That is not filler language. It means the abrasive is designed to resist clogging and loading, which helps the paper stay usable longer and keeps the surface cutting more evenly. When abrasive loads up, finish quality drops and work slows down. This design is aimed squarely at avoiding that problem.

The high-strength resin bond is another jobsite-relevant detail. It supports the abrasive grain so the cutting surface stays more stable under use. On a sanding roll, that matters because you are often pulling off exactly what you need and putting it to work across different tasks, from quick touch-up prep to more repetitive bench or bodywork sanding.

The listed roll size is 360 inches long by 4.5 inches wide, giving you a lot of usable abrasive in one roll. That longer format is practical for shops and serious users who burn through sheets and would rather cut custom lengths to fit the task instead of being locked into pre-cut pieces.

This Mirka sanding roll is a smart fit for auto body prep, finishing work, general surface prep, and shop use where controlled sanding and reduced loading matter more than brute-force stock removal. If you want a dependable abrasive roll from a known finishing brand and you prefer to cut your own working lengths, this one is built for that kind of workflow.
