A problem you would encounter if you spray lacquer on a polished silicone surface?

• A. Fisheye
• B. Caulk
• C. New plaster walls
• D. Disposable brush

Answer: (A)

When a coating can’t wet the surface properly, you get fisheye—tiny crater-like pits that form where the paint pulls away around dust, oils, or residues. Polished silicone has extremely low surface energy and resists wetting by lacquer, so the coating beads up and can’t level smoothly. You’ll see circular imperfections around any contaminant or slick area, which is characteristic of fisheye. The other options don’t describe this wetting/adhesion problem. Caulk, new plaster walls, or a disposable brush aren’t the wetting issue you’d expect when spraying lacquer on a non-wettable surface like polished silicone; they don’t explain why the lacquer fails to film and forms those round voids around contaminants.
