Fixing Fiberglass Stress Cracks with Andy from ‘Boatworks Today’

Boat maintenance and repair expert and master YouTuber, Andy Miller, is busy in his Wisconsin shop this winter. He’s taken an old Bertram Moppie powerboat (epic yacht, if you ask me and many others) and is redoing someone else’s restoration. Andy knows too much to settle for bouncy decks and thin areas of fiberglass.  He’s getting right to work on important structural areas where he feels the prior owner skimped on glass. His foredeck looked sharp, but a boatload of trouble lies underneath all the beautiful gelcoat, and Andy knows just how to fix it.

  1. These videos are great because you can apply them to other types of woodworking as well. I also like the fact that the products are also available. Keep up the great work.

  2. I am a novice at glass work but this production made me comfortable with taking a stab at some of the smaller projects that my boat needs.

  3. Great partnership. Andy is a master craftsman and Totalboat’s has great products. I learn more from watching Andy, than any other YouTube DYI boat videos, that I can use on my boat. He always explains what he is doing and the products he is using in detail so you not only know the how but also the why. That is how you gain the knowledge, to not only do the project you are working on at the moment, but you also know on future projects, what to do and how to do it.

  4. I’ve been watching your channel for some time now and have learned very much from your videos.
    I see you are using Jamestown laminating epoxy that does not need sanding between coats.
    What is the difference between that product and West system 105/ 205,206….. epoxy.

  5. As always, another great video, Andy. Agree with your endorsement of JD and their Total Boat line of products. What weight mat are you using there? Any tips on what weights for what applications have worked best for you? Thanks, again for doing this helpful video.

  6. I used to do a lot of fiberglass work (surfboards) and had never used TotalBoat until a couple of years ago. I ordered a gallon of poly laminating resin to do a series of repairs on in-ground fiberglass duck blinds and was pleased with the product, except for one significant problem. I did the job outdoors in October in Southern California and temps were around 102F. Even with the jug of resin in the shade, the stuff jelled on me, in the jug, by the end of the first day, making it totally unusable. No catalyst contamination, just high ambient temps. Found out later that there is a summer formulation but JD shipped me the winter blend. Be careful out there.

  7. Hi Chris, Andy was using a polyester laminating resin. Completely different from epoxy and the West system.
    There are many differences. I would highly suggest the downloadable resin guide from Boatworks Today, as well as some of Andy’s previous videos as a great place to learn more about the differences and applications associated with different types of resins. Hope this helps.

  8. This is a great video , I learn a lot , Will be fixing stress cracks on my 31′ JC deck and flybridge, After watching Andy , I am ready to tackle the job , Will use Total boat products.

  9. I am not clear on why you need to have PVA or wax on the surface to get a cure. What is it providing?

    Also curious, as some of the others in this comment section about how you are going to treat the edges of the repair. Are you just going to sand off the fibers and then blend with more gelcoat? If this is the case, aren’t you causing a problem with applying PVA. I thought PVA was a mold release … ie prevents adhesion.

    Glad to have the videos. Many thanks.
