Your choice of a fairing board for marine sanding, fairing and finishing can mean a lot for your results and your budget, and our 3M™ Hookit™ Flexible Marine Fairing Board helps you maximize both. This lightweight, 4-1/2” x 30” marine longboard features a one-level, two-handle design that lets you grasp it and handle it securely and effortlessly across irregular surfaces. This marine longboard has a flexible facing for smoothness and consistency in applications such as hull fairing, sanding curves and concaves and finishing plugs and molds. When sanding, our 3M™ Hookit™ attachment system saves time by making sheet changes fast and easy.

The Hookit™ hook-and-loop attachment on our Hookit™ Flexible Marine Fairing Board works with 3M™ Hookit™ abrasive sheets to save you time and expense. The facing side of the board features brushed nylon loops that instantly grip the J-shaped hooks on Hookit™ abrasive sheets. It’s simple: just slap on the sheet and start sanding. The sheets remove just as cleanly and easily, making it easy to re-use them again and again for the extent of the abrasive life.

Our Hookit™ Flexible Marine Fairing Board is another way that 3M applies science to your life – and makes your marine fairing and sanding easier and more efficient.
