Glassfiber filler is a 2-component, glassfiber-reinforced polyester filler.
Suitable applications include the repair of rust damaged car bodies, reinforcing profiles or beams, on certain repair work on boats etc. We most emphatically warn against the use of glassfiber filler to repair through-hull holes in GRP boats, since the reinforcement effect of the glassfiber filler is not sufficiently high for this purpose. Surface cracks in this type of boat may be repaired perfectly satisfactorily.
