Assess and Understand 'Fish Eye' Contamination

What happens here

Begin by observing the painted surface for any signs of 'fish eye' – circular craters or dimples in the finish. These indicate contamination on the substrate that repels the wet paint, preventing it from adhering uniformly. The presenter emphasizes that these need to be properly addressed before applying any further coats to achieve a smooth and professional finish.

Goal: The presenter introduces the problem of 'fish eye' in a paint finish, which is characterized by small, crater-like depressions caused by surface contaminants. He explains that simply repainting over these imperfections will not resolve the issue, as the 'volcanoes' (raised edges of the fish eye) will still be visible.
