3Mâ„¢ 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 3Mâ„¢ 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.
3Mâ„¢ Marine High Strength Repair Filler comes in a paste consistency that can be applied on vertical surfaces. It offers a working time of 10 to 15 minutes and may be sanded in 30 minutes.
