Tell us the job and the surface. We'll lay out the exact grit progression — coarse to fine, dry or wet, DA or block — plus the abrasives to run it. No guesswork, no burned-through panels.

Strip to metal, level filler, grind welds.
P150–P320

P400–P600
Scuff & block
Adhesion scuff, block primer-surfacer.
P800–P1500

P2000–P5000
Wet-sand & polish
Final finish before compound & buff.
Grit guidance is a starting point — test on a hidden area and follow each product's data sheet. Step grits gradually; skipping too far leaves scratches the next grit can't remove.
