Prime the Putty and Re-spray

What happens here

After sanding the glazing putty smooth, it is critical to prime the area before applying the topcoat. The presenter uses a spray primer to cover the puttied spot. This is important because some topcoats can have a chemical reaction with the glazing putty, causing bubbles or pinholes if not properly primed. Once the primer is dry, use a paint sprayer to apply a uniform coat of paint to the entire masked-off section of the trim, ensuring complete coverage and a smooth, professional finish that hides the original paint run and any repairs.
