How to Restore the Shine to Fiberglass Boat Gelcoat— BoatUS Magazine

Fiberglass boats require regular maintenance to keep them looking good.  The gelcoat surface can become dull and weathered due to age, sun, air, and water.

The good news is that this can be repaired.  The shine can be brought back to new condition.

BoatUS contributing editor Lenny Rudow gives a webinar on how to maintain and polish fiberglass gelcoat into a showroom shine. He discusses how to keep boat hulls looking in top condition. After years of boat ownership and testing every boat polish, compound, and wax, he shares his favorite products and describes how best to apply them.

BoatUS Magazine is the flagship publication of the Boat Owners Association of the United States. The award-winning magazine is delivered bimonthly to more than half a million BoatUS members and focuses on up-to-date issues, maintenance projects and skills that every boater should know.


Four Layer Epoxy Pool Coating Application

Swimming Pools are a harsh environment for composites materials.  They have some advantages compared to other materials, but are still affected by the sun, chemicals and temperature.  Composites materials become damaged over time, and repair may be required.

Composites materials can also be used as a coating repair on top of other materials such as concrete.  The epoxy seals cracks and smooths the surface for a cleaner look.

It is very important to use the correct tools and materials and follow the proper order of operations.  Once all of this work is complete, you will have a very nice swimming pool!

Truck Camper DIY- How to Build

Pickup Truck owners have been adding slide-in campers for many years.  There have been commercially built units for many years.  It is also possible to build one yourself.  The tools are widely available, the techniques are easy to learn, and the designs are up to you.

This video gives you a look at how I built my lightweight truck camper. The camper was built with everyday tools most people have. It is a one piece fiberglass unit. The camper weighs 630lbs dry and approximately 900lbs loaded. This camper was made to fit my 2004 Dodge Dakota. Every part of the camper was custom made except the windows and rear door which were taken from an older aluminum camper.

Repairing a cracked kayak hull

Epoxy and fiberglass can be used to successfully repair hull and deck cracks.
There are some important steps to follow, and the correct materials must be used.

Epoxy resin bonds very well to many materials, including kayaks made of ABS, fiberglass, and epoxy resins.

Youtube user Mark Jones shares his experience:

Hurricane brand kayaks are repaired with epoxy and fiberglass. A final gel goat application makes the repair disappear.


Custom composite parts made from carbon fiber and epoxy can be made at your own workshop should you have the proper equipment, knowledge, and materials.

Doing epoxy resin infusion with carbon fiber reinforcement is pretty advanced, but is possible.

Here is an example that includes the process of building a custom mold:

In this video I show you how to make a laptop case in carbon fiber from start till finish! This is a pretty advanced tutorial that should show you some insights on how I’ve made it. The laptop used in this tutorial is a Lenovo thinkpad X1 Carbon… for more specs on the laptop if needed.

I’ve decided to share the progress on how I’ve build it on here. I know it very hard to make something like this at home without the right equipement but I hope this will inspire you in some way. At least it will show you how carbonfiber parts are made in the F1/bike/race/space industry

It all starts with drawing everything in fusion 360 to do a virtual fit in 3D. After that I’ve used my X-carve from inventables to cut out the exact shape. Have a look at to find more about the X-carve

Once carved I’ve decide to route all the sides of the pre-mould to get a nice rounded edge on de MDF. MDF is a type of ‘wood’ that will suck up a lot of moist/water/resin. That’s why I’ve Decided to coat it with an epoxy resin, tinted with red pigment. polished it all and proceeded with the mouldmaking.

Everything starts with the release-agent. after that I use the entire uni-mould mouldmaking kit from Easycomposites for all the products used in this video.
First layer is the gelcoat, after that the coupling coat with a 100g/m chopped strand fiberglass. On top of that there is the polyester tooling resin with 4 layers of fiberglass chopped 400g/m

Let both halves cure, bolt them together and trim off the excess edges. time to demould and remove the piece, wetsand to a high gloss and get the mould ready to make the parts.

Used a technique called VARTM or resin infusion to create high end carbon fiber parts. Lay-up is 3 layers: 200 twill weave, 650 twill weave, 200 twill weave. peelply on top and infusion mesh to finish. time for bagging and tacky tape with all the connectors in place.
Used the infusion resin IN2 from Easycomposites and infusion was done.

Wetsand and trim the parts, glued them up and your done!!!

How to fix stripped screw holes in fiberglass boat using epoxy & fibers

Epoxy resin can be used to repair problems with fiberglass boats.  One such instance is the problem of having screw holes that are stripped out.

Grinding out and replacing the material will allow for a new, fresh hole to be made for your screw.

Carbon Fiber Fabrication | Making A Engine Accessory Bracket

Carbon Fiber / Epoxy materials have many uses and advantages.  With a high strength to weight ratio and appealing aesthetics, it can offer a unique and custom touch to custom vehicles.

Using a CNC-controlled router to cut a part that will create custom shapes and sizes will allow for great fit and finish on your project!
