How do you use gloss?

How you use gloss depends on whether you are referring to gloss paint or cosmetic gloss, but in both cases the key is careful, even application for shine and protection. For gloss or semi-gloss paint, you first need to prepare the surface thoroughly because gloss shows imperfections. Clean the surface, repair holes, sand smooth with fine grit sandpaper, and apply a primer, especially if painting over bare wood, drywall, or a previous glossy finish. Stir the paint well, do not shake vigorously to avoid bubbles. Use a high-quality synthetic brush for trim and doors or a short-nap microfiber or foam roller for larger flat areas to minimize stipple. Apply thin, even coats, maintaining a wet edge to avoid lap marks, and avoid over-brushing. Two coats are usually needed, with light sanding with 220 to 320 grit between coats. For cosmetic gloss like lip gloss, start with exfoliated, moisturized lips, apply lip liner if desired, then apply gloss from the center outward using the applicator, and blot slightly if needed. For hair gloss, apply to clean damp hair according to product instructions, leave for the recommended time, then rinse.
