CRC ADOS Plastic Putty 3L Medium Weight Polyester Filler For Auto Marine DIY Fast Cure No Shrink Sandable

CRC ADOS Plastic Putty Can 3L is a medium-weight, all-purpose polyester filler designed for serious repairs across a wide range of surfaces. Its chemical-curing formula delivers a premium, gap-free finish without the shrinkage that plagues ordinary air-drying fillers.

• Unmatched versatility: ideal for car bodies, boats, trailers, caravans, bricks, concrete blocks, wood, masonry, metal, fibreglass, most plastics and more.
• No shrinkage: cures by chemical reaction, so you avoid shrinking, sinking, or pullback after application.
• Fast-curing and smooth: easy to apply, sands to feathered edges, and resists sagging during cure.
• Excellent adhesion: bonds aggressively to diverse substrates for durable, long-lasting repairs.
• Sagging and pin-holing resistance: specially formulated to maintain shape and surface integrity as it cures.
• Tack-free finish: cures to a tack-free surface that is compatible with basecoat/clearcoat systems, eliminating staining or bleeding of the final coat.
• Sandable and paintable: ready for sanding, filling, and top-coating to achieve a professional, showroom-ready finish.
• Heritage and reliability: part of CRC’s ADOS family, continuing the trusted lineage of Mendent Plastic Putty for consistent results.

Practical use cases and application guidance

• Automotive body repairs where a smooth, warp-free finish is critical—fenders, panels, and repaired seams benefit from the no-shrink, tack-free cure.
• Marine and boatwork: repairs on hulls and decks where moisture resistance and durable adhesion matter.
• Hobby, DIY, and home projects—repair bricks, concrete blocks, wood, and metal surfaces with a single, versatile filler.
• Fibreglass and plastics: a reliable base for further finishing without basecoat staining or bleeding.

Tips for best results

• Prepare the surface: clean, dry, and lightly abrade to promote adhesion.
• Mix and apply in thin coats; allow each layer to set before adding the next to prevent sagging.
• Finish with a compatible basecoat/clearcoat system to achieve the final color and gloss you want without staining or bleeding.
• Sand to your desired feathered edge and prime if needed before final painting for a showroom shine.
