2. Sanding
Using fine-grit sandpaper and a sanding block, gently sand the paint runs. Work in a circular motion, applying light pressure. Gradually increase the grit of the sandpaper to smooth out any imperfections.
3. Cleaning
After sanding, thoroughly clean the area with a tack cloth to remove any sanding dust. Wipe down the surface with a clean cloth dampened with rubbing alcohol.
4. Rubbing Compound
Apply a small amount of rubbing compound to a microfiber towel. Rub the compound onto the sanded area in a circular motion, following the direction of the paint flow. This will help to level out any remaining imperfections and restore the shine.
5. Polishing Compound
Once the rubbing compound is applied, use a clean microfiber towel and a small amount of polishing compound to further enhance the shine and gloss. Apply the compound in a circular motion, working in sections.
6. Final Inspection
Inspect the area carefully for any remaining imperfections. If necessary, repeat the sanding, rubbing compound, and polishing steps until you achieve a flawless finish.
