Polish vs. Sealant vs. Ceramic: Which Is Best for Your Aircraft’s Exterior?
A glossy finish is always satisfying, but not every product that creates shine protects your aircraft. For maintenance crews and owners, understanding the difference between polish, sealant, and ceramic coating is key to keeping paintwork both beautiful and durable. Each has its own role, from restoring oxidised paint to creating long-term protection — and the right choice depends on how your aircraft is used, stored, and maintained.
Aircraft Polish: Restoring Shine, Not Protection
Polish is designed to restore an aircraft’s appearance by removing oxidation, surface haze, and minor scratches. It uses fine abrasives to smooth the paint or metal surface, bringing back depth and gloss. However, polish itself offers no lasting protection, it simply enhances appearance and should be followed by a sealant or coating to preserve the finish.
Highlights:
- Intended Use: Removes oxidation and light surface imperfections
- Components: Fine abrasives and cleaning agents
- Longevity: Short-term cosmetic improvement
- Ideal Scenario: Aging or dull paintwork, pre-show detailing, or prep before protective application
Recommended Product: Aircraft Metal Polish
Sealants: Affordable Protection with a Synthetic Shield
Sealants provide a protective layer on top of the aircraft’s paint, offering a balance between ease of use, affordability, and protection. Made from synthetic polymers, sealants defend against UV exposure, water spotting, and dirt accumulation while leaving a smooth, glossy finish. They are easy to apply and ideal for aircraft that undergo regular cleaning or are stored outdoors.
Highlights:
- Intended Use: Creates a synthetic protective film on painted or composite surfaces
- Components: Polymer or anti-static synthetics
- Longevity: Typically 3–6 months per application
- Ideal Scenario: Regularly washed aircraft or those exposed to outdoor elements
Recommended Product: Polymer Sealant or Anti-Static Polish
Ceramic Coatings: Premium, Long-Term Protection
Ceramic coatings represent the next level in paint protection. They chemically bond to the surface, forming a hard, transparent layer that resists UV rays, chemicals, and contaminants. The resulting hydrophobic surface repels water, oil, and grime, making cleaning easier and reducing long-term maintenance. Although more costly upfront, ceramics can last up to two years or more, ideal for high-value or frequently flown aircraft where appearance and protection are top priorities.
Highlights:
- Intended Use: Creates a long-term, molecular-level barrier
- Components: Advanced ceramic or silica-based compounds
- Longevity: 12–24 months or longer, depending on environment and upkeep
- Ideal Scenario: Premium aircraft, fleets, or operators seeking reduced maintenance frequency

Choosing the Right Option for Your Aircraft
When deciding between polish, sealant, and ceramic coating, consider:
- Aircraft Usage: Is it flown daily or occasionally?
- Environment: Is it exposed to salt air, dust, or strong UV?
- Maintenance Routine: Do you prefer regular detailing or minimal upkeep?
- Storage: Is the aircraft kept in a hangar or outdoors?
Your answers will guide whether you prioritise quick enhancement (polish), affordable protection (sealant), or long-term defence (ceramic).
