Answer
For super glue on plastic, level carefully with 600, then refine with 800, 1000, and 1500.
Why it happens
Glue residue is harder than the plastic surface and needs careful leveling.
Recommended grit
Use 600 for raised glue, then 800, 1000, and 1500 to refine.
Wet or dry
Wet for fine stages when the plastic can handle it.
Success check
The glue spot is level and the surrounding plastic is not gouged.
What to do
- Scrape only loose glue carefully first.
- Level raised glue with 600 grit.
- Refine with 800, 1000, and 1500.
- Polish if the plastic needs clarity or gloss.
Avoid: Do not start with coarse grit on visible plastic.
