Klenk's Fish Eye Eliminator eliminates the effect of fish eyes. Fish eyes, nasty little pea-sized craters in a finish film, occur when the wet finish's surface tension keeps it from flowing over slippery contaminants on the work. Silicone oil is by far the most common culprit in fish eye formation. Sources of silicone contamination found while bathtub repainting include silicone caulking residue, silicone grout sealer and silicone found in hairspray. Silicone contamination is also common in furniture refinishing, since many furniture polishes contain silicone oil.
