Patch Minor Imperfections3M™Acryl Putty fills minor surface blemishes in cars, trucks, vans, boats and other vehicles. Our acrylic glazing putty offers excellent workability with easy and smooth spreadability that effectively conceals pinholes, sand scratches and other spot repairs. Once the putty fully cures, you#39;ll appreciate its low rate of shrinkage and excellent adhesion to the surface.Better Feathering Means Less WorkOur spot putty offers high quality feathering properties, meaning it is easy to smooth out the edges to blend with the surrounding surface. Good feathering will produce more satisfactory results and reduce sanding.Choose the Putty that ,s Right for You3M™Acryl Putty comes in multiple formulas offering different rates of drying, working time and sanding time.
