Common Concerns Answered
Will this disc adhere properly to my sander?
The Hookit attachment system is designed for secure and reliable grip on corresponding Hookit backup pads, ensuring the disc remains in place during operation.
Is P120 grit suitable for fine finishing?
P120 grit is an intermediate grit, ideal for initial material removal and shaping. For a smoother finish, follow with finer grit discs after using this P120 disc.

These discs are constructed with durable aluminum oxide and a robust backing, engineered for longevity in demanding marine applications, though exact lifespan varies with pressure and material.
Frequently Asked Questions
What is the primary application for P120 grit sandpaper in marine settings?
P120 grit is commonly used for removing oxidation, old paint, rust, and moderate imperfections from fiberglass, gelcoat, and metal surfaces prior to subsequent refinishing steps.
Can I use these discs on a standard random orbital sander?
Yes, provided your random orbital sander is equipped with a compatible 5-inch Hookit backup pad. The Hookit system is widely adopted for its ease of use and secure attachment.
What is the benefit of the Hookit attachment system over PSA?
The Hookit system allows for quicker disc changes and is generally more resistant to loading up with dust, offering a more consistent abrasive surface and easier alignment compared to Pressure Sensitive Adhesive (PSA) discs.
Are these discs suitable for dry sanding only?
While designed for dry sanding, the durable construction may allow for limited wet sanding applications depending on the specific task and lubricant used, though wet sanding is not the primary intended use.
How does the 5-inch diameter benefit a boater?
The 5-inch diameter is a standard size that fits most common random orbital sanders, offering good coverage for various hull and deck areas without being excessively large or difficult to maneuver for detailed work.
