Premium Polyester Finishing Putty

High‑Quality Body Filler for Auto Repair

The Polyester Finishing Putty offers a reliable solution for repairing dents, small scratches, gouges, or surface imperfections on car bodies. As a two‑component (2K) polyester filler, it bonds well to metal, aluminium, fiberglass, older primers, and many other substrates. Because of its versatile adhesion, it works on steel panels, plastic bumpers, SMC, and even slightly flexible parts.

Smooth Application & Easy Sanding

Mix the putty with its hardener according to the instructions (usually a small percentage). Then apply a thin, even layer over the damaged area. The material spreads smoothly and levels out bumps or dents without sagging. Once cured, it sands down quickly and evenly — leaving a smooth, ready‑to‑paint surface. This process reduces prep time and helps you get a high-quality finish under paint.

Versatile Usage Across Substrates

You can use this putty on bare metal, galvanized steel, aluminium, fiberglass, old body filler, painted or primed panels (after proper sanding), and many plastic components. This makes it a go‑to for collision repair, rust patching, filler feather‑edging, or surface smoothing after welding or body‑work.

Fast Curing & Practical Workflow

Thanks to the 2K polyester chemistry, the putty hardens quickly (usually in minutes at normal temperature). As a result, you save time compared to older heavy fillers. After curing, you can sand with 180‑220 grit for shaping and finish with 320‑400 grit for priming. This speed helps keep repair workflows efficient and reduces stall time between filler and paint.

Durable and Paint‑Ready Surface

Once properly sanded, the putty forms a strong, stable base that accepts primers, basecoats, and clearcoats without issues. Because of its dense filling and adhesion, it resists shrinking and remains stable under coatings. This ensures long-term durability for repaint work, even on repaired panels.

Suitable for Professionals and DIYers

Whether you run a busy auto‑body shop or work on DIY restorations at home, this putty adapts well. Its easy mix‑and‑apply format, fast curing, and universal adhesion make it useful in many scenarios: dent repair, rust patching, filler feather‑edge smoothing, small dent work, and panel refinishing.
