What should be done immediately if paint runs occur during application?

1. Wait for the paint to dry before reapplying

2. Sand down the run and reapply the paint

3. Apply a clear coat to cover the run

4. Remove all paint and start over

The correct answer is: Sand down the run and reapply the paint

When paint runs occur during application, the most effective immediate response is to sand down the run and reapply the paint. This approach allows for correction of the surface irregularity without compromising the underlying layers. Sanding the run helps create a smooth, even surface that promotes good adhesion for the new layer of paint. Waiting for the paint to dry before addressing the run can lead to additional complications, such as a harder-to-sand surface or further imperfections. Applying a clear coat over the run does not fix the issue and can lead to an uneven finish and problems with the final appearance. Completely removing all paint and starting over is often unnecessary and time-consuming, especially when a localized fix can efficiently resolve the issue. Therefore, sanding and reapplying is the most practical and effective solution to manage paint runs during the finishing process.
