Common Concerns Answered
How does the 320 grit perform on delicate surfaces?
The 320 grit is a fine abrasive, ideal for achieving smooth finishes without causing deep scratches on most marine surfaces, including gelcoat and painted metal. It's suitable for the final stages of preparation.
Will this sheet load up quickly in damp marine environments?
This sheet is designed with abrasion resistance in mind, helping to reduce loading and maintain its cutting efficiency even when working with marine materials which can sometimes create dust or residue.
Is this suitable for removing heavy rust or paint?
For heavy rust or paint removal, coarser grits like 80 or 120 are typically recommended. This 320 grit is best for finer finishing, surface preparation, and smoothing existing surfaces.
