The sun is shining, the weather is warm, and the weekend forecast promises to be more of the same. You know exactly how you intend to spend it: watching the sun wake up over the water, while you lure in some fish in your fiberglass boat.

Before the weekend arrives, you check your boat over to make sure you have all the fishing equipment you need need and that she’s in tiptop shape. That’s when you see it: a small hole in her side.

If this happens to you, don’t worry. Small cosmetic holes are very easy to fix.


Gather Your Supplies

Before you begin, you will need to gather and prepare a few supplies. Heres what you will need:


  • Acetone


  • Waxed Fiberglass Resin

→ We recommend using a waxed fiberglass resin for small holes because the wax will rise to the surface of the patch and prevent air from stopping the resin from hardening.


  • MEKP (methyl ethyl, ketone, peroxide) catalyst

→ The amount of MEKP catalyst will change depending on how much resin you have, what the outside temperature is like, and whether or not your boat is in the ocean. So make sure you follow the chart on the back of the resin jug to ensure you’re using the correct amount.


  • Container for mixing


  • Stirring Stick


  • Fiberglass fabric cut to size

→ We recommend that you purchase the tape because it creates a neater edge


  • Throw-away brush



    When gathering your supplies don’t forget to think about yourself too, and put on some protective clothing and gloves.




Clean the Area around the Hole

After you’ve gathered everything you need, the first step is to clean the area around the hole with acetone to make sure there are no contaminants such as waxes, silicone sprays, or dust on the surface because they can affect the way the resin adheres to the surface.



Mix the Resin for One Application

You will need to mix enough fiberglass resin for one application. For this step, you will need the resin, the MEKP catalyst, the mixing container and the stir-stick.


When you are mixing the resin and the catalyst remember to scrape the sides of the container to make sure you’ve used all of the catalyst. You will also want to avoid whipping the mixture, as this causes air bubbles. The final thing you’ll need to remember is to only mix enough for one application. Once the resin is mixed with the catalyst nothing will stop the thermal reaction from happening, which means it will harden before you’re ready for the next coat.



Patch the Hole

Once the resin is mixed, brush it over the clean surface on your boat. Then place the tape over it. Finally, brush more resin on top of the tape. Doing it this way ensures that there is enough resin both underneath and on top of the tape to seal it properly.

If you need to put another layer on, wait 15-20 minutes before preparing another batch of resin.


Once it’s completely set, you can get back to waiting for the weekend to show up so you can reel in some fish. We hope this post has been of help for you. Have any comments? Let us know!
