The Complete Indasa Finishing Process

A flawless finish isn't one product — it's a system. Indasa is built as a fully integrated surface-finishing range, where each line hands off cleanly to the next: strip and shape, refine, pre-polish, then compound to a mirror gloss. Follow the stages below to build the right kit and skip the guesswork.

Stage 1 — Strip & Shape (40–80 grit)

Heavy stock removal: leveling filler, stripping old coatings, shaping panels. Reach for the most aggressive grits on a tough backing.

• Discs: Red Line grip & PSA discs (premium, longest life) or White Line for everyday value
• Boards & strips: long-board rolls and file-board strips for straight-line leveling
• Metal: Rhynofibre fiber discs and Rhyno Flap discs for grinding and weld dressing

Stage 2 — Refine (120–320 grit)

Shape filler, prep primer, and lay a uniform scratch pattern for topcoat. This is where most body-shop prep time is spent.

• Discs: Red Line / White Line / Plus Line vacuum discs in 120–320
• Dust-free: HT Line ceramic and Mesh Line for fast, cool, clog-free cutting
• Hand work: sanding blocks, foam hand pads and Rhyno Sponge pads for edges and contours

Stage 3 — Pre-Polish (400–3000 grit)

De-nib, color-sand, and erase orange peel before buffing. Film-backed and foam abrasives give the most uniform scratch for an easy polish.

• Film Line: Rhynogrip Film Line discs (240–1500) for ultra-uniform finishing
• Wet & dry: Rhynowet sheets up to 2500 grit for color sanding
• Foam: Rhynocell (3000) and Rhynofinish foam discs as the final pre-polish step

Stage 4 — Compound & Finish

Cut and refine to a deep, swirl-free gloss with the Autogloss system.

• Cut: Autogloss Compound Plus with the white foam cutting mop
• Gloss: Autogloss High-Gloss Plus with the black foam finishing mop

Don't forget the platform

Great abrasives need the right tool and a clean panel:

• Backup pads: match the hole pattern and grip/PSA backing — shop Grip Backup Pads and PSA Backup Pads
• Sanders & extraction: pneumatic and electric DA sanders plus Dust Extraction for a cleaner, faster shop
