ADOS Fibre Filler’s unique chemically engineered formulation of resins and aluminium, forms a filler of exceptional strength and adhesion with no shrinkage. It supersedes other fibre fillers by eliminating the need to weld patches which causes panel distortion. Once set it is an ideal product for filling or bridging large holes and gaps in steel, fiberglass and most other materials. ADOS Fibre Filler sets as hard as steel, yet is easy to use and work before curing. It is compatible with basecoat/clearcoat systems and is ideal for use on motor vehicles, caravans, trailers, boats and guttering. It is recommended to use ADOS Plastic Putty/Body Filler over the Fibre Filler for final fairing and finishing.
