How Do You Restore Old Gelcoat?

If you’re lucky enough to have an older boat with Gelcoat in good condition, you can keep it looking shiny and new with a little elbow grease. 

Here’s how to restore an old Gelcoat: 

1. Start by washing the Gelcoat with a mild soap and water solution. Use a soft brush or sponge to avoid scratching the surface. 

2. Rinse the Gelcoat thoroughly and allow it to dry completely. 

3. Once the Gelcoat is dry, you can begin polishing it with a commercial wax or polish specifically designed for use on boats. Apply the product evenly using a clean, soft cloth. 

4. Buff the Gelcoat until it has a nice shine. You may need to apply several coats of wax or polish to achieve the desired results.

How Do You Restore Heavily Oxidized Gelcoat?

If you are lucky enough to catch your Gelcoat before it becomes too heavily oxidized, you can restore it with a polishing compound. Polishing compounds contain abrasives that will remove the oxidation and leave behind a shiny, new surface. 

Be sure to use a rubbing compound, not a cutting compound, as cutting compounds will damage the Gelcoat.

If your Gelcoat is severely oxidized, you may need to have it professionally sanded and refinished. This is a much more involved process than simply polishing and should only be attempted by someone with experience.

How Do I Fix Dull Gelcoat?

If you have a dull Gelcoat, the first thing you need to do is identify the cause. There are a few different things that can cause Gelcoat to become dull, so it’s important to figure out what’s causing the problem before you start trying to fix it. 

One common cause of dull Gelcoat is oxidation. This happens when the Gelcoat is exposed to sunlight or other sources of ultraviolet (UV) light for extended periods of time. The UV light breaks down the polymer chains in the Gelcoat, causing it to become brittle and lose its shine.

To fix this type of damage, you’ll need to sand away the oxidized layer and then polish the Gelcoat with a rubbing compound. Another common cause of dull vis physical damage.

The damaged area will usually look duller than the rest of the hull because the top layer of Gelcoat has been abraded away. To fix this type of damage, you’ll need to sand away the damaged area until it’s flush with the surrounding Gelcoat, and then polish it with a rubbing compound. 

Finally, another common cause of dull Gelcoat is contamination from oil or other chemicals. This can happen if someone spills something on your hull or if your boat sits in a marina where there’s a lot of fuel and oil floating around in the water. 

To clean off this type of contamination, you’ll need to use a degreaser followed by a good quality boat soap. Once you’ve cleaned off all the contaminants, you can then polish the hull with a rubbing compound to restore its shine.


Boat owners need to be aware of the damage that can be done to their boat’s Gelcoat, and know how to properly restore it.

Gelcoat restoration is a process that takes time and patience, but it is worth it in order to protect your investment. By following the steps we have outlined in this blog post, you can ensure that your boat’s Gelcoat looks as good as new.
