Answer
For spray paint orange peel, wet sand cured paint with 1000 or 1500, then 2000 and 3000.
Why it happens
The surface texture must be leveled only after the paint is dry enough to sand cleanly.
Recommended grit
Use 1000 or 1500 for light orange peel, then 2000 and 3000 before polishing.
Wet or dry
Wet.
Success check
The surface has an even fine haze with the texture leveled.
What to do
- Let the paint cure enough to sand cleanly.
- Wet sand lightly with 1000 or 1500.
- Refine with 2000 and 3000.
- Polish if gloss is required.
Avoid: Do not wet sand soft or uncured paint.
