Buying Guide
When it comes to choosing the best polish for your fiberglass boat, there are a few key features to keep in mind. By considering these factors, you can make an informed decision and ensure that you choose a product that will meet your needs.
1. Type of Polish
There are two main types of polish for fiberglass boats: wax-based and polymer-based.
Wax-based polishes are typically easier to apply and remove, but they may not last as long as polymer-based polishes. Polymer-based polishes are more durable and provide a longer-lasting shine, but they can be more difficult to apply and remove.
2. UV Protection
UV protection is an important feature to consider when choosing a polish for your fiberglass boat.
The sun’s UV rays can cause damage to your boat’s gel coat, which can lead to fading, cracking, and other issues. Look for a polish that offers UV protection to help prevent this damage.
3. Abrasion Resistance
Abrasion resistance is another important factor to consider when choosing a polish for your fiberglass boat.
Your boat is likely to come into contact with a variety of surfaces, including other boats, docks, and debris in the water.
A polish that offers good abrasion resistance can help protect your boat’s gel coat from scratches and other damage.
4. Application Method
Finally, consider the application method when choosing a polish for your fiberglass boat. Some polishes require a buffer or other special equipment, while others can be applied by hand.
Choose a polish that fits your skill level and the tools you have available.
Consider these points to pick the right polish for your fiberglass boat and keep it looking good for years.
