What happens here

After the primer has dried for two days, it is sanded to remove any remaining lint from the roller, smooth out the surface further, and address any minor imperfections that became visible after priming. An Ekasand 3x4 orbital sander is used with 320-grit Filmtek abrasives for flat areas and an Ekasilk sanding sponge for contours. The presenter emphasizes avoiding excessive heat build-up while sanding to prevent gumming up the abrasive or damaging the coating. He also mentions a small brush (1.5 inch Fat Boy brush with nylon polyester blend) is used for 'laying out' paint on the trim around the glass panels, because the narrowness of the trim. The goal is a super smooth surface ready for the final topcoat.

Goal: Achieve a perfectly smooth surface by sanding the dried primer coat, removing lint and minor flaws.
