Buying Guide
Key considerations when selecting a rubbing compound for heavy oxidation include cutting power, finish quality, substrate compatibility, and application method. Here are important factors to weigh:
- Cutting power vs. finish: Heavier cuts remove oxidation quickly, but may leave more haze. Look for products that balance aggressive cutting with a high-gloss finish.
- Substrate compatibility: Gelcoat, fiberglass, painted metal, and clear coats respond differently. Ensure the product lists your surface type as supported.
- Application method: Some compounds are suited for hand use, others for machine polishing. If you plan to use a buffer, verify pad compatibility and recommended RPM ranges.
- Pad and equipment pairing: Foam or wool pads affect heat and removal efficiency. Use recommended combinations from the manufacturer or trusted detailers.
- Residue and cleanup: Silicone-free formulas reduce cleanup time and prevent residue interactions with sealants or waxes.
- Finish and protection: Some products pair with a follow-up polish or dedicated marine wax to prolong the restored look against UV and salt exposure.
- Safety and usage: Professional-grade products may require ventilation and eye protection. Follow label directions for safe use and disposal.
