The goal of fairing is to create a surface without bumps or hollows.
Fairing Compound should be of a consistency that can be troweled onto a surface without sagging. Add 407 Low Density or 410 Microlight filler to mixed epoxy, checking the consistency as you stir in the filler to determine if the mixture has the correct viscosity for your application.
While most of our customers are successful when using WEST SYSTEM Epoxy to repair damaged fiberglass, we have become familiar with some common mistakes that are easily preventable. These mistakes are made by both professionals and amateurs. The information discussed in this article is available in our Fiberglass Boat Repair Manual and WEST SYSTEM User Manual, and on the WEST SYSTEM website.

The amount of wood used in a production fiberglass boat is significant; it is used for many things such as stringers, bulkheads, floors and backers. Higher quality production boats often use marine grade plywood for these applications but it can still be damaged by long term exposure to water. Continue reading →
Many of our EPOXYWORKS articles feature projects that our customers have spent years building and represent major personal accomplishments. I also believe we have many customers who, like me, use WEST SYSTEM Epoxy simply to keep an older boat in good repair.
The following are examples of repairs and small projects that I have completed on my personal boat over the last ten years. These would apply to many production fiberglass boats. Since WEST SYSTEM Epoxy has a shelf life measured in years, it is easy to keep it on your shelf and tackle these tasks when it’s convenient. Continue reading →
January 2013 was a big month for the Gougeon Brothers, Inc. Technical Department. This department is responsible for our technical customer service, product development and quality control. In January this department moved into a completely new building that adjoins our current facility. Continue reading →
Fiberglass reinforced plastic and other composites influence the design of many products manufactured today. Boat hulls, sports equipment and airplanes can easily take new, complex shapes when composites are used in place of traditional materials. Reinforcing structures also benefit from the versatility of composite materials when prefabricated components are bonded with a high-strength adhesive. This article will discuss some of the engineering aspects to consider when designing or repairing an adhesively bonded composite structure.Continue reading →
Boat builders or advanced hobbyists often want to learn more about the characteristics of the fiberglass laminate they’ve just created. But sending samples to a professional testing laboratory can be expensive and impractical. Fortunately, there are some tests you can do in the shop that yield reasonably accurate results.
Before you begin to test laminates in your own shop, it’s important to understand the difference between shop tests and standardized tests. Many organizations such ASTM, ISO, or UL provide established test procedures defining a specific test method. These may specify things like sample preparation methods, equipment and acceptable environmental conditions. These standards allow the test to be repeated by different people at different locations all over the world. Continue reading →
Ted Moores and his company, Bear Mountain Boats, build wood epoxy strip plank canoes, manufacture kits and publish books on building strip plank canoes and kayaks. This method of construction provides a very light yet stiff structure and also enables the hull shape to have compound curves. Moores has 30 years of experience and his designs have logged many safe miles. He understands the forces boats are subjected to when paddled on the water and during transportation. Continue reading →
My personal boat is a 1986 Formula 242 LS.With a soft riding deep V hull, good performance and a small but well appointed cuddy cabin, it is a great boat for me, my wife and our dog to use for a whole weekend. One shortcoming, besides not having standing headroom in the cabin, is the built-in cooler located in the cuddy cabin. The cooler had a side door and was styled to look like a refrigerator. This may have looked “cool” in the mid 1980s but was impractical. We couldn’t put ice in the cooler without having the water leak out through the door. For any trip longer than one night I had to use a standard cooler strapped to the swim platform. This was inconvenient and limited the use of the platform at the beach. Continue reading →
My wife’s 2000 Audi TT has a very sleek shape, and these smooth lines are carried under the hood with molded plastic engine covers that provide a very clean looking engine. Unfortunately when I was servicing a burned out bulb, I attempted to remove the covers in the wrong sequence which caused a tab to snap off. Continue reading →
