Answer
Remove bulk tape residue first, then sand lightly with 220 or 320. Use 400 for final prep.
Why it happens

Success check
The surface is smooth, clean, and no longer sticky.
What to do
- Remove as much adhesive as possible before sanding.
- Use light pressure with 220 or 320.
- Wipe residue often.
- Finish with 400 before painting or refinishing.
