Fiberglass Fill to Repair our Oliver Hulls


Recommended Posts

I asked this question on a mod thread, "Does anybody know a good fill product for screw holes in fiberglass?" This is an important subject, so I started a new discussion. And thank you @aaronorange for suggesting Marine-Tex Epoxy for this purpose. MARINE-TEX® EPOXY PUTTY - ITW Performance Polymers

I have witnessed at least a dozen threads here where members have replaced shore power or solar terminals, and many other items screw-mounted where the screws have cracked the fiberglass. Many have just remounted as-is or used larger screws, into the cracked hole. If the screw hole is cracked, a proper repair would include filling and redrilling the hole.

Our hull needs so many fiberglass repairs that I will work this summer. With all of my automotive experience, "autobody" has never been a strength. Never owned or repaired a fiberglass boat either. I have two 3/8" holes in the interior hole from removing the original TV mount. There is a small hole in the front made by a stone and a blemish behind the AC which looks like somebody banged it with a tool. I will remove the Dish Satellite and OMG the amount of damage OTT created in installing the dish is crazy.

I like the Marine-Tex suggestion as I have learned that ITW also produces Permatex, a trusted product line that I have used in automotive work for 3-4 decades. I would also like to learn from your experiences and more about "how-to?" Besides suggested products, what are best practices in fiberglass repair work. Thank you for any advice you can provide!

I like the white marinetex, as I've suggested many times, for minor projects.  It's always in our supply locker, as in most boaters.

It's "pretty close" to our Oliver color, "pretty close" to the boat color, to fill in screw holes. 

If you cover the filling with saran wrap or tape (remove promptly after set), it stays fairly glossy. And smooth. Wprk on cooler days (70s) No need in inobtrusive areas to gel coat, as you would need to do with bondo or fiberglass paste. . Which is a pita.

If you don't like the end result, it's easy to drill out and redo. 

There are many videos out there on YouTube.
