Bondo glass reinforced Filler provides fiberglass quality repair of small holes and rust outs (up to 1/2 in) without the need for backing strips, fiberglass mat or fiberglass resin. This reinforced body filler contains short, interlocking fiberglass strands, making it twice as strong as standard body filler and much easier to use during vertical repairs. If your repair needs even more strength, it also works well with traditional fiberglass repair materials and tools.
