3M 7000045479 Acryl-white Putty 14.5 Oz Tube

Product Description

The 3M 7000045479 is an acrylic-based white putty formulated to fill pinholes, light scratches, and other surface defects on automotive and marine substrates. Supplied in a 14.5 oz tube, it spreads smoothly with a putty knife or spreader and sands easily once cured. Its white pigmentation reduces the risk of color bleed-through when topcoating with white or light-colored finishes, a common issue with tinted or gray putties. Low shrinkage helps maintain a flush surface after drying, reducing the number of re-application passes needed before finishing.

This putty is intended for body repair and surface prep work on automotive panels and marine surfaces where minor defects must be corrected before priming or painting. It suits both shop technicians and experienced detailers working on light collision repair, restoration, or touch-up applications. The product is packaged in single tubes with a minimum order quantity of 12 units, making it appropriate for shop stocking.

Installation Notes

Application is typically performed by auto body technicians or marine finishing professionals. Clean and degrease the substrate thoroughly before applying putty to ensure proper adhesion. Allow the putty to dry fully before block sanding to achieve a flat, feathered edge. Prime the repaired area before topcoating per standard body shop finishing procedures.
