3M Company LS-QT-ES Fiberglass Reinforced Filler 32 Oz

Product Description

The 3M COMPANY LS-QT-ES is a long strand fiberglass reinforced body filler supplied in a 32 oz (2 lb) container. It is formulated with extended fiberglass strands blended into a polyester resin base, providing structural reinforcement and high tensile strength in filled areas. This filler is suited for repairing rust-out panels, holes, and severely damaged substrates where standard short-strand or non-reinforced fillers lack the structural support needed. Body shop technicians and auto restoration professionals apply it as a base layer before finish coats of conventional body filler or glaze.

This filler is used in automotive body repair, marine hull patching, and general fiberglass substrate restoration. It is appropriate for both collision repair shops and professional restoration work where substrate integrity has been compromised. The long strand construction bridges larger voids and open areas more effectively than standard filler, making it a common choice for rust repair and panel reconstruction before final surface finishing.

Key Features

• Long strand fiberglass reinforcement for structural bridging across holes and voids
• Polyester resin base provides strong adhesion to metal, fiberglass, and similar substrates
• 32 oz container size suits shop use and multi-panel repair jobs
• Designed as a base-coat filler, compatible with topcoats of standard body filler or glaze
• Packaged individually; sold in cases of 6 units

Compatibility

Designed as an OEM-style replacement filler for automotive body repair applications requiring fiberglass-reinforced structural fill prior to finish-coat body filler or glaze.

Installation Notes

Application should be performed by experienced body shop technicians or qualified restoration professionals. Mix catalyst thoroughly per manufacturer instructions before applying to a clean, bare, and scuffed substrate. Wear appropriate PPE including gloves and respiratory protection when mixing and sanding fiberglass-reinforced materials. Sand cured filler before applying finish coats to ensure proper adhesion.
