Buying Guide
What to consider when choosing gel coat touch up products
- Damage scope: For small chips and scratches, touch-up pens (white or black) are typically sufficient. For deeper gouges or cracks, a repair kit or gel coat repair paste is preferable.
- Color matching: White is common, but tintable options and pigments help replicate your hull’s exact color. Test a small area first.
- Finish and durability: Look for high-gloss marine-grade paints with UV protection and corrosion resistance for exterior surfaces.
- Application ease: Built-in brushes or simple mixing instructions ease DIY repairs. Consider whether you want a self-contained pen or a larger kit.
- Cure and durability: Some options require curing time and catalysts. Ensure you have adequate ventilation and follow safety guidelines.
Practical tips for best results
- Prepare the surface: Clean, dry, and lightly sand the repair area for optimal adhesion.
- Apply thin coats: Build up color gradually to avoid runs and sags.
- Test color match: On a hidden area, then proceed to visible spots.
- Follow curing instructions: Temperature and humidity influence cure time and gloss level.
