Description of π¦ Optimum 4240 Silicon Carbide Sanding Finish
320 grit sheets are best for wet sanding and feathering paint, or use dry to smooth and shape body fillers. Made with a premium grain, which offers a higher cut rate and uniform scratch pattern which makes it perfect for achieving fine finishes. When sanding wood, 320 grit sheets are best for scuff sanding between clear coats and sealers. Use dry during the preparation phase of a project, usually when removing existing finishes, rust and oxidation; it is also key when sanding and shaping body fillers and primer coats. Sheets can be cut-to-fit 1/2 sheet, 1/3 sheet, or 1β4 sheet sanders.
Pros
- Manufactured with premium grit for faster cutting speed and consistent scratch pattern, ideal for finishing
Cons
- Unsafe
Pros
- Use dry during project preparation, typically to remove existing finishes, rust and oxidation; this is also important when sanding and shaping putties and primers
