Wet Sand the Trim Surface

What happens here

Dip the medium-grit 3M sanding sponge into the bucket of water and wring out any excess. Keeping the sponge wet is crucial as it lubricates the surface, preventing the paint from heating up, gumming, and sticking to the sponge. Begin wet sanding the area where the paint run was, using gentle pressure and circular motions to smooth out the surface and blend the repaired area with the surrounding trim. Wipe the area with a rag to clean off any sanding residue and inspect the progress.
