What grit sandpaper should I use?

60-80 grit for heavy material removal and paint stripping. 120 grit for general shaping. 150-180 grit for pre-stain sanding. 220 grit for between-coat sanding. 320+ grit for ultra-fine finishing between topcoats. Start with the coarsest grit needed and progress through each grit level.

How do I avoid swirl marks?

Use consistent, light pressure — let the sander do the work. Move slowly in overlapping passes. Do not start or stop the sander while it contacts the surface. Sand through each grit level completely before progressing. Finish with 220 grit and wipe with a tack cloth to reveal any remaining marks.
