![]() ![]() How Can You Deal With The Fisheye-A Quick Prevention And Remediation Tutorialīefore we get started, let’s take a look at a definition of the auto paint phenomenon commonly known as fisheye.We’ll address that question in this post, and the answer might surprise you a bit. Install an air filtering system that removes and prevents oil and moisture contamination.We get that question a lot from our clients.Thoroughly clean the surface to be painted with detergent and hot water, followed by the recommended solvent cleaner.Do not use fisheye eliminator in undercoats or basecoat color. If fisheyes appear in a basecoat, allow the color to flash then spray a mist coat over affected area. ![]() Add the recommended fisheye eliminator and respray the affected area.Remove wet paint film with solvent, clean and refinish.Make sure that all products containing silicone are used as far away from the workshop as possible.Regular maintenance of air supply/equipment.Thoroughly degrease surface with a wax and silicone remover.Improper or insufficient surface cleaning or preparation.Spraying over previously repaired areas containing “fisheye eliminator” additive.Use of thinner/reducer in place of a solvent cleaner.Effects of old finish and previous repair (May contain excessive amounts of silicone).Contamination from use of polishes or aerosol spray containing silicone.Contamination of the surrounding air (proximity to mechanic shop).Contamination by soap residues, detergents or metal cleaning products. ![]() Contamination by wax, silicone, oil or grease.Therefore, in this instance the finish should be dried, sanded and repainted. If during the second coat the fish eyes are not bridged, it is highly unlikely that a third coat will accomplish an acceptable result. After the paint is fully cured, if slight remnants of the fish eye are visible, it can be sanded and polished. A third coat is applied, not only for full coverage but also to make sure that there is sufficient paint for detailing later. If fish eye does occur, particularly in the first coat, often painters will let that coat fully tack off, then follow it by a second coat, which often “bridges” the fish eye so that it becomes invisible. If the surface has been properly cleaned and degreased using a wax and grease remover, fish eye can usually be prevented completely. These fish eyes are produced because the coating is unable to wet out the contaminated area.įish eye is a preparation defect. When a coating is applied to a substrate that is contaminated with low surface energy particles such as oil, wax, grease or silicone, fish eyes may develop in the coating as it is applied. Fish eyes can be caused by oily spots or silicone particles and/or by airborne droplets that are deposited on the painted surface. They are small quasi-circular areas of substrate that are exposed through the applied coating immediately after application and which have at their center a source of contamination. They are usually caused by oil and grease on a coating substrate.įish eyes are also known as silicone contamination, poor wetting, saucering, pits, craters and cissing.įish eyes are a typical defect when paint is sprayed. Fish eyes are small, crater-like openings in the finish after it has been applied. ![]() Fish eyes are a type of coating defect which is characterized by circular voids or separation in the coating. ![]()
