Evercoat Poly-Flex Flexible Polyester Glazing Putty — 30 fl oz for Bumpers & Plastics, Sandable Flexible Repair

Evercoat Poly-Flex is a flexible polyester glazing putty formulated to spot-fill, skim-coat, and smooth minor surface damage on flexible bumpers and plastic automotive parts.

Poly-Flex combines a flowable viscosity with flexible cured properties so it adheres to substrates that move or flex, making it suitable for common cosmetic repairs. The product is supplied with a blue cream hardener for controlled working time and cures to a sandable surface that accepts paint or primer. Evercoat has produced professional-grade fillers and putties since 1953 and developed this formulation to meet the demands of collision repair shops and DIYers working on modern plastic components.

How does Poly-Flex perform on flexible bumpers and plastic panels?

Poly-Flex is designed to remain conformable after curing, reducing the risk of cracking on parts that flex during normal use. It bonds to a variety of plastic and composite substrates when properly prepared, and its flowable consistency helps it fill low spots without excessive shrinkage.

• Flexible cured film suitable for bumpers and trim
• Low-shrink formulation for minimal rework
• Good adhesion after proper surface preparation
• Flowable viscosity that fills sand scratches and small gouges

What types of blemishes and repairs is this putty best for?

Use Poly-Flex for spot filling small imperfections and skim-coating repair areas where the original paint remains intact. It excels on sand scratches, nicks, dings and minor gouges that need a smooth, sandable finish before primer or topcoat.

• Sand scratches and surface abrasion
• Small dings, nicks and shallow gouges
• Skim coating over repaired or painted areas to level surfaces
• Touch-ups on steel, aluminum, fiberglass and many plastics

How do you mix, apply and sand Poly-Flex for best results?

Measure the blue cream hardener and polyester putty by volume, mix until uniform, and work quickly within the working time. Apply in thin layers for best adhesion and reduced curing stress; once cured, the material sands easily with 180-grit followed by finer grits for finishing.

• Mix putty and hardener thoroughly in small batches
• Apply thin, controlled layers for skim coating or spot filling
• Cures to a sandable finish—start with 180 grit for shaping
• Clean and scuff substrate before application for improved bond

Will Poly-Flex work under paint and primer, and what surfaces are compatible?

After proper surface preparation and sanding, Poly-Flex accepts primer and most topcoats, making it suitable as a prep step before painting. The product is compatible with common automotive substrates, including metal and many plastics, when recommended adhesion steps are followed.

• Accepts primer and topcoat when prepped correctly
• Suitable for steel, aluminum and fiberglass panels
• Formulated for many plastic and composite substrates used in bumpers
• Best results when following standard adhesion and cleaning procedures
