Origin and Potential Causes: · Unsuitable thinner or reducer for application conditions. · Materials not uniformly mixed. · Spraying too wet. · Holding spray gun too close to work. · Uneven spray pattern. · Incorrect spray PSI or gun setup · Low shop temperature. · The flash time of the base coat was too short before the clear coat was applied. · Coat affected by wet or humid air/weather. Prevention Techniques: · Select the thinner or reducer that is suitable for existing shop conditions and mix properly. In cold, damp weather, use a faster-dry solvent. · Stir all pigmented topcoats - especially metallics - thoroughly. · Use proper gun adjustments, techniques, and air pressure. · Keep your spray gun clean (especially the needle fluid tip and air cap) and in good working condition. · Do not spray metallic base coats too wet. · Keep spray gun parallel to panel. · Follow application recommendations per the Technical Data Sheet Remedy: · Allow color coat to set- up and apply a drier double coat or two single coats, depending upon which topcoat you are applying. · If the defect is only visible after the application of the clear, thoroughly dry the clear, sand and refinish. |
