Indasa Rhyno Sponge Double-Sided Hand Sanding Pads – Ultra Fine 600–1000 Grit, Wet or Dry Foam Block (595145)

Overview

The Indasa Rhyno Sponge Ultra Fine (Part #595145) is a double-sided foam hand sanding pad engineered for ultra-fine finishing passes on automotive clear coats, gel-coat, composite materials, primers, and varnish. Color-coded blue for the 600–1000 grit range, it delivers a conformable, pressure-equalizing sanding surface on edges and curved surfaces — wet or dry. Sold in boxes of 100 pads, it is built for high-volume production environments.

Key Features

• Double-sided abrasive faces – two usable surfaces per pad, extending service life and reducing pad changes
• Pressure-equalizing foam core – distributes hand pressure evenly across curved and contoured surfaces, preventing oversanding and edge burn-through
• Aluminum oxide grain with flexible resin bond – maintains sharp cutting action through repeated wet and dry passes
• Blue color-coding – instantly identifies ultra-fine grit range (600–1000) in multi-grit workflows, eliminating mix-ups
• Wet or dry rated – use dry for paint and primer; use wet with water or lubricant for clear coat and gel-coat micro-finishing
• Box of 100 pads – production-scale quantity for body shops and finishing lines

Application Suggestions

• Automotive clear coat: Final wet-sanding passes before machine polishing; removing P1500–P2000 sanding scratches on curved panels and door edges
• Gel-coat & composite: Ultra-fine surface prep on boat hulls, fairings, and composite panels before buffing
• Primer & filler: Smoothing high-build primer on contoured surfaces prior to base coat application
• Varnish & lacquer: Between-coat flatting on furniture and cabinetry; final denib pass before polishing

Compared to Alternatives

• vs. Indasa 3100B double-sided sponge (P60–P240): 595145 targets ultra-fine finishing (600–1000 grit) while 3100B covers coarser stock removal and shaping. Use 3100B first, then finish with 595145 for a complete hand-sanding sequence
• vs. Wet/dry sanding sheets (Rhynowet): The 595145 foam pad conforms to 3D curves without a separate block; Rhynowet sheets on a flat block are better suited for flat panel work requiring a precise, flat scratch pattern
• vs. Generic ultra-fine sponges: Indasa's flexible resin bond maintains abrasive integrity through repeated wet passes, where cheaper sponges delaminate or lose cut quickly
