Applied directly from its easy dispensing tube, Bondo® Glazing & Spot Putty is formulated for quality repairs in less time. Its 1-part nitrocellulose formula eliminates mixing and helps to keep small repairs simple, efficient and on schedule. It is non-staining, so it won't affect the color of paint or finishes around the repair area. It also shrinks very little over time, helping to ensure lasting repairs without rework. This spot and glazing putty is ideal for spot repairs and other small repairs. Use it for filling pinholes as well as for covering minor sand scratches, and more on metal, fiberglass and wood as well as sanded and primed or sanded and painted surfaces.
