Applying fiberglass filler to automotive or other fiberglass surfaces requires care and precision to achieve a smooth, durable result. Here's how you can do it simply and accurately at home.

Fiberglass putty is used on fiberglass surfaces and in various fields of application such as, for example, the nautical one. It is the useful and indispensable tool for filling, correcting and leveling imperfections, drafts and damage, even of large thicknesses. It is, in fact, a layerable and excellently resistant filling putty that allows anyone to carry out small do-it-yourself repairs.

Obtain the best quality products and accessories needed for the small repair:

Usually, it is a two-component putty like The Care Fiberglass Putty with the catalyst already included in the package to make it harden correctly.

If you need to apply multiple layers, let each layer dry completely before applying another. Fiberglass Putty is designed to be layered without forming cracks or bubbles and to be finished with a finishing putty such as Standard Putty White to obtain a perfectly level and smooth surface
• Leveling and Shaping : After applying the fiberglass filler, use the putty knife or scraper to shape and level the surface so it is as smooth as possible. You can slightly moisten the tool to facilitate processing. Try to get a smooth surface with no dips or bumps
• Drying : Allow the grout to dry completely. Drying time varies depending on the type of grout and environmental conditions. Follow the manufacturer's instructions and make sure drying is complete and perfect
• Sanding : Once the putty is completely dry, use sandpaper of various grits to smooth the surface. Start with a coarse grit to remove any imperfections and then proceed with finer grits to achieve a smooth finish
• Cleaning : After sanding, clean the surface thoroughly and make sure to remove all residues of filler and dust. You can use a degreaser such as Degreaser with TNT Cloth non-woven cloths or a green microfibre cleaning cloth such as Microfibre Cloth green
• Finish : If desired, apply a smooth finishing putty such as Standard Putty white or a porous one such as Standard Putty gray for a flawless finish and follow with an appropriate primer on the repaired surface to protect it and prepare it for painting
