3M Company SS-PT-ES Fiberglass Reinforced Filler 21 Oz

Product Description

The 3M COMPANY SS-PT-ES is a short strand fiberglass reinforced filler designed for filling and repairing large voids, rusted-out areas, and damaged sections where standard body fillers lack the structural reinforcement needed. The fiberglass strands within the filler matrix add tensile strength to the cured repair, resisting cracking and shrinkage over time. Sold in a 21 oz unit, it is well suited for body repair professionals, auto technicians, and skilled tradespeople working on metal, fiberglass, and composite substrates. Each case packs 8 units for shop stocking convenience.

This filler is typically applied in automotive body repair, marine repair, and general fabrication scenarios where voids are too large or structurally demanding for conventional polyester filler. It performs in residential and commercial shop environments and is a common choice when a repair area requires added fiber reinforcement before final finishing and priming.
