Questions About Boat Surface Maintenance
Q: Why should I maintain my boat’s gelcoat surface?
Gelcoat is designed to protect your boat’s structure and shine. Regular maintenance prevents UV damage, mould, and moisture from breaking down the surface – and keeps your boat looking great longer.
Q: Can I restore a faded or dull gelcoat surface?
Yes! With the right polishing and protection, it’s possible to restore shine and extend the life of your gelcoat for 15 years or more.
Q: What causes oxidation on boats – and how do I prevent it?
UV rays and lack of surface protection cause oxidation, leaving your boat’s surface dull, chalky, and rough. Using Mirka’s 4-step system – especially Final Finish + Marine Shield – helps stop oxidation and restore gloss.
