Lightweight Polyester Cosmetic Filler - Clearance

High Quality No-Shrink Surface Filler

Lightweight Polyester Cosmetic Filler is a versatile, creamy paste designed to fill, seal, repair, and finish surface damage on composite materials. When applied, it quickly forms an exceptionally rigid and strong surface which can easily be sanded to a feather edge. It will not shrink, sag, or pin-hole after curing, and it can accept virtually any paint or finish without any special surface preparation. This thixotropic filler delivers excellent physical and cosmetic properties.

Apply catalyzed #4116 Lightweight Polyester Cosmetic Filler with a spatula or putty knife. After 15-20 minutes, it can be sanded to final finish.

Use #4116 Lightweight Polyester Cosmetic Filler for automotive finishing, filling in surface porosity, and a number of repair applications including bass boat hulls; composites; vacuum molds; tub and bath applications; urethane molds and parts; and cracks, dents, and crevices on worn surfaces. When cured, this filler adheres to fiberglass, SMC, RIM, BMC, plaster, graphite, KEVLAR®, steel, iron, and copper.

For applications that require a structural repair, first use #4130 Polyester Fairing Compound. #4100 Polyester Fairing Compound is a fibrous putty used to rebuild broken, void, or damaged areas. Once cured, apply #4116 Lightweight Polyester Cosmetic Filler over the repair to achieve a smooth, cosmetic surface.
