Determine Type and Extent of Damage and Starting Point
- Crazing – A series of very fine lines, stars, or haze when viewed at an angle in bright light. Crazing is
below the surface and usually cannot be felt with the fingernail. Requires aggressive sanding to
remove. Begin with 220 grit wet/dry sandpaper.
- Deep Scratches – Easily felt with the fingertip Begin with 220 grit wet/dry sandpaper.
- Minor Scratches – Readily detected with a fingernail. Begin with 1500 Micro-Mesh. If the scratch is not
easily removed use 400 wet/dry sandpaper followed by Micro-Mesh 1500.
- Hairline Scratches & Light Scuffs – Light scratches and hazing – Begin with 2400 or 3600 Micro-Mesh
- Very Fine Scratches – Usually caused by improper cleaning methods. Begin with 4000 or 6000 MicroMesh.
Crazing is the most common and objectionable problem with regards to aircraft transparencies. It appears to be scratched, either large or small, which when highlighted by the sun show up as bright lines. In reality, they are shallow fractures just under the surface layer. Crazing can be classified into two categories, minor and severe. Minor crazing has the appearance of thousands of tiny scratches on the surface. When viewed at an angle to the sun or a bright light, they look like a network of very fine shiny lines, stars or haze. Severe crazing, has fewer scratches, but they are much larger and appear to be deep gouges in the surface. In both cases it is rare that these can be felt with the fingernail – they are UNDER the surface. This will be the hardest type of damage to remove. Deep crazing will require sandpaper, possibly as coarse as 120 grit. Crazing removal will take time. An equal amount of material must be removed from the entire surface to prevent distortion. THIS MUCH STOCK REMOVAL CAN ONLY BE DONE WITH SANDPAPER. DO NOT BE AFRAID TO USE SANDPAPER ON YOUR TRANSPARENCY! After damage removal and completion of the sandpaper sequence, the cloudy appearance will be removed as you continue with the Micro-Mesh procedure.
