3M 7100143457 Plastic Spreader Set Body Filler Assorted

Product Description

The 3M 7100143457 is an assorted plastic spreader set designed for applying body fillers and finishing putties in automotive bodywork applications. The set includes three spreader sizes — 4 inches, 5 inches, and 6 inches — giving technicians the flexibility to work across a range of panel contours and surface areas. Each spreader is made from flexible plastic, allowing controlled application and smooth feathering of filler material. This set is a general-purpose tool appropriate for body shops, collision repair facilities, and automotive refinishing work where consistent filler laydown and a clean spread are required before sanding and finishing.

This spreader set is suited for use on any vehicle during body filler and finishing putty application. The three included widths accommodate narrow seams and small dings as well as broader panel repairs, reducing the need to keep multiple separate tools on hand. Technicians use these spreaders to press, distribute, and shape two-part body fillers and finishing glazes before the material cures. The flexible plastic construction conforms lightly to curved surfaces, helping to minimize pinholes and air pockets in the applied filler.

Installation Notes

These spreaders are a hand-applied tool used by automotive body technicians and collision repair professionals. Before use, ensure the surface is properly cleaned, sanded, and free of contaminants to promote filler adhesion. Mix body filler per the filler manufacturer's instructions before applying with the spreader. Dispose of used spreaders or clean thoroughly before the material cures, as hardened filler will compromise the flexible edge needed for clean application.
