For effective sanding of soft materials, the ProSand A975 fine grit paper H&L vacuum disc excels. It features a flexible B-weight latex backing and P-graded seeded-gel ceramic alumina abrasive, delivering quick cuts and long-lasting performance. The non-pigmented No-Fil coating minimizes surface loading, while vacuum holes ensure fine dust is whisked away, making it perfect for demanding jobs on soft metals and composites.
