A Strong Two-Part Filler for Marine Repair
3M™ Marine High Strength Repair Filler is a uniquely modified vinyl ester structural filler formulated with short strand fiberglass for non-fairing applications. The fiberglass fibers interlock to give our filler additional strength compared to regular fillers. Filler is non-staining, non-shrinking and it comes with 3M™ Marine Creme Hardener.
We recommend this product for filling and covering scratches, dings, rust-outs, blemishes, pinholes and other simple surface defects that otherwise exhibit a true or fair line. Use this filler to level or even out depressions and low spots.
