Hiding power comes from the paint's pigment and is affected by the manner and thickness of the application. Color retention is the ability to maintain its original color during exposure to sunlight, etc. Chalking resistance prevents the white chalky powder from forming on the surface and lightening the color of the paint. Chalking occur over a period of time. Blister resistance keeps excessive moisture from coming through the substrate and affecting the paint layer.
