Dissolve Decals & Details But Leave The Paint
 
Gel formula cleanly fades or removes factory applied letters and numbers with minimal or no damage to underlying paint. Allows you to control what detail and how much is removed. Use on plastic, metal or wood. Not suitable for models that use the same ink/paint on both body and details.
