- UV and Salt Resistance: Prioritize UV blockers and salt-water resistance for sun-heavy or coastal environments.
- Gloss vs. Protection: Decide if you want a high-gloss finish, a protective barrier, or a balance of both.
- Ease of Use: Consider cure and buff requirements; easier applications save time on regular maintenance.
- Maintenance Schedule: Some products are best applied seasonally, others monthly; align with your boating frequency.
