Answer
Sand only the clear coat on carbon fiber. Wet sand with 1000, 1500, 2000, and 3000 before polishing.
Why it happens
Carbon fiber parts often have a clear coat over the fiber. Sanding too deep can expose or damage fibers.
Recommended grit
For clear coat only, use 1000, 1500, 2000, then 3000 wet before polishing.
Wet or dry
Wet for clear coat finishing to reduce dust.
Success check
Only the clear coat is refined, with no exposed or damaged fiber.
What to do
- Identify whether you are sanding clear coat or exposed fiber.
- Use dust protection and keep the area controlled.
- Wet sand clear coat with 1000, 1500, 2000, and 3000.
- Stop before reaching the fiber weave.
Avoid: Do not sand into exposed carbon fibers.
