Buying Guide: Key Considerations For Deep-Scratch Glass Polishing
What level of scratch do you need to fix?
Use deep-scratch repair kits for scratches you can feel with a fingernail. For faint or light haze, lower-grain or finishing formulas may suffice. Choose a kit that matches the depth and area you plan to restore.
What size work area will you polish?
Small areas require compact 2” or 3” kits with precise control. Larger projects benefit from 5” systems and a compatible rotary polisher for efficient restoration.
What surfaces are included in your project?
Decide if you’re polishing windshields, car windows, mirrors, tables, or aquariums. Some kits are optimized for automotive glass, while others suit general surfaces and household use.
What tooling and accessories are needed?
Many kits include cerium oxide powder, polishing pads, abrasives, and backing pads. Confirm compatibility with your drill or polisher (thread size and speed) before buying.
Is there a caution or limitation you should know?
Deep scratches across large areas may require professional repair or larger-format kits. Some kits are best for targeted spots rather than comprehensive surface restoration.
