Fiberglass Putty for Strength and Flexibility

Fiberglass Putty is a professional 2K polyester putty reinforced with fiberglass. These fibers in the putty provide extra strength and flexibility, making the filler suitable for larger surfaces and deep dents. Fiberglass Putty is easy to apply and after drying it is easy to sand, resulting in a smooth and even surface. Due to the combination of polyester putty and fiberglass, this filler is durable, water-resistant, and tear-resistant. The filler can be used on various materials such as metal, wood, plastic, and concrete, making it suitable for both DIY projects and professional applications. At CROP, you will find top-quality fiberglass putty from brands like FINIXA, Presto, MoTip, and our own CROP Premium brand.
