Which grit is specified for wet sanding the entire panel when preparing for pearl basecoat blend?

• A. 1500 grit
• B. 1200 grit
• C. 800 grit
• D. 2000 grit

Answer: (A)

Wet sanding for a pearl basecoat blend needs a very fine, even scratch pattern that lets the new layer lay down smoothly and feather into the surrounding paint without leaving noticeable sanding marks. Using 1500 grit achieves that balance: it lightly levels the surface, smooths out texture, and creates a gentle fade into adjacent color so the pearl can blend evenly rather than showing scratches or edges. The other grits don’t fit as well. An 800 grit is too coarse and would scratch or remove too much material, making the blend hard to finish cleanly. A 1200 grit is slightly coarser than ideal for feathering and may not give as seamless a transition. A 2000 grit is very fine and is typically used for final polishing after clear coat, not for preparing the basecoat blend, where you still need enough bite to feather and level the surface.
