Apply First Coat of Shellac-Based Primer

What happens here

Using an airless spray gun, apply a uniform, thin coat of Zinsser B-I-N Shellac-Base Primer over the entire surface, paying close attention to the areas with 'fish eye'. The shellac primer acts as a strong barrier against bleed-through and adhesion issues caused by contamination. The presenter specifically mentions using a spray application method for this step.

Goal: To encapsulate the contaminants causing the 'fish eye', a shellac-based primer is applied over the affected areas. This creates a barrier that prevents the contaminants from affecting subsequent paint layers.
