Answer
For resin print support marks, use 400 or 600, then refine with 800 and 1000.
Why it happens
Support marks need careful leveling without flattening nearby detail.
Recommended grit
Use 400 or 600 for small support marks, then 800 and 1000 for finer smoothing.
Wet or dry
Wet for fine stages after the resin is fully cured.
Success check
Support marks are blended without removing nearby detail.
What to do
- Make sure the resin print is fully cured.
- Level support marks with 400 or 600.
- Refine with 800 and 1000.
- Clean residue before primer or paint.
Avoid: Do not use coarse grit on detailed resin parts.
