Modelcraft Glass Fibre Detail Pencil (2mm)
The Modelcraft PBU2138 (glass fibre pencil) is used for highly precise sanding, scraping, and cleaning in tight spaces where traditional sandpaper is too large or clumsy. Because glass fibre is rigid yet flexible, it allows you to target specific spots to remove debris or surface layers without damaging the surrounding material.
Here are the most common applications, grouped by category:
1. Scale Modeling & Miniatures
- Removing glue residue: Sanding away excess superglue or plastic cement from seams on plastic, resin, or metal models.
- Stripping paint and primer: Scraping away paint mistakes locally or clearing paint from joints to ensure a strong plastic-to-plastic bond when gluing.
- Smoothing flash and mold lines: Cleaning up tiny imperfections and rough edges on plastic parts straight out of the sprue.
2. Electronics & Repairs
- Cleaning contact points: Removing corrosion, rust, and battery acid leakage from battery terminals (like in old remote controls), circuit boards (PCBs), and switches.
- Fixing soldering errors: Scraping away excess solder or removing the protective solder mask to expose copper traces on a PCB for repair.
3. Automotive & Small DIY Projects
- Targeting rust spots: Precisely scraping out deep rust inside tiny stone chip damages on car paint before applying a touch-up pen.
- Polishing metals: Cleaning corroded screw threads, watch parts, coins, or small jewelry.
4. Arts, Crafts & Household
- Erasing ink and stains: Literally "sanding" away stubborn ink lines or stains from heavy paper, cardboard, or parchment (a classic drafting technique).
- Etching and weathering: Creating matte effects, scratches, or distressed textures on glass, plastic, and soft metals to achieve a weathered look.
