  • This week I tackle blister repair on my sailboat's rudder. I followed a step-by-step guide from BoatUS.com for blister repair. Hope you find this useful if you're doing the same DIY project. Let's continue getting this boat reading for sailing!
    List of supplies:
    A rotary sander; a face mask or respirator; a Dremel tool; protective eyewear; a cleaning brush; optional rubbing alcohol; rubber gloves; paint brushes; disposable spoons, knifes, and cups; epoxy (West Systems 105); hardener (West Systems 206 or 205); colloidal silica (West Systems 406); and fiberglass fabric.
    Boat: 1985 Beneteau First 38

    Great video and thanks for sharing. Just a little pointer, instead of a knife to apply the paste, best to use a plastic scraper. I use old credit cards and cut them into various sizes. I use a thinner section to first apply the past then force the past deep in to the affected area. I force the past all 4 ways , back, forth, up and down to ensure the hole/clevis is completely filled and air bubbles removed. I then apply a bit more past and use a full size card to achieve and almost perfect repair with almost no sanding required. Experience and sharing information is the key.

It can certainly be frustrating at times because boats seem to always break and need something else fixed. But it's a process and that's the fun part. Cheers!

    Hi Josh, and thanks. I once set out to build a kayak, which required the use of the "West System". I read all their information carefully, and clearly recall that the new fibreglass should not be sanded for 14 days, as the uncured fibreglass dust can cause chronic lung problems . Here is the info from West Sytems Owners Manual:
    " Breathing dust from epoxy that is not fully cured increases your risk of sensitization. Although epoxy cures quickly to a sandable solid, it may take over two weeks
    at room temperature, or post-curing, to cure completely" . fyi

    Just discovered your channel. What a great instructional video in the use of fiberglass repair. You just got a new Sub. Many like myself feel intimidated because of a lack of "basic" knowledge in the use of fiberglass when it's not really that difficult. You make it easy to understand and take the mystery out of it. Vlogging entertainment is great....but instructional videos are of great interest and value to many. Keep up the good work. That's how we get through life....sharing knowledge with others. Thanks for sharing.

    Nice work and Video josh you did a excellent job on the narration and the video content a few minor things i do a little different instead of a Dual Action sander i use a grinder with a Sanding disc attachment on it because that grinds way faster i grew up in South Florida and i had a business that i worked on Boats and Yachts as a teenager i used to take on many Bottom jobs and that Grinder trick helped me to prep the hull free of Barnacles and Bottom paint bye i’m 56 years old now and in the 1970 and 80s they didnt have or use a Barrier coat over the Gelcoat i got paid by the job not hourly so the faster i got things done the more i made and down there we had a steady flow of vessels was that Fawcetts the one in Annapolis ?? i kept a Boat in Deale MD for over 20 years and used to run up to the Fawcetts there for some items the folks that worked there were very knowledgeable and they had a large plotter that could print full size paper charts for any where in the world you desired sure i use modern technology but ive navigated all over the World using paper Charts plus they are a little Nostalgic to me on places ive visited before with hand written notes and even contacts and names of locals that helped me out in those parts its always nice to reunite and maybe even share a few cocktails with people yu share common interests with ive kind of found putting those notes into a computer or electronics just doesn’t have the same feel to it ? i guess i am from a generation that would take the time out to hand write a card or letter and mail it to that person and thats not something your age does or cares about as you look to be about the age of my own children at this time

    the reasons blister appear in the first place is because of improper application of the gel coat to the fiberglass. This could happen for several reasons. A: Cold weather when the hull was first built. B: Very damp weather when the hull was built. C: Glass coat was not "tacky" when gel coat was applied. With boat hulls made in permanent molds the mold is first waxed, then the gel coat is applied. By the way gel coat is nothing more then fiberglass resin with color pigmentation added to it. While the gel coat is still tacky the fiberglass is shot into the gel coat to form the basic hull. If this is done in damp weather or cold weather the fiberglass may not fully adhere to the gel coat -- blisters will appear at a later date. when repairing blisters it is important to not just sand the gel coat but to sand until you reach the fiberglass. If this isn't done you are guaranteed to have problems in the same area in a short time.

      After watching too much BoatWorks and SailLife, I THINK you might have wanted to bevel those pits out a bit more to cover a wider area, with a few layers of glass, increasing in size with each.
      I certainly don't have any personal experience though, and I'm not sure I've seen spots this small tackled before, so I may be completely off base and you've done a solid, professional quality job here for all I know. No offense intended!
      Either way, I really enjoyed your "How to sail" video. You really nailed making it approachable for beginners like myself. Thanks! Inspiring stuff...

      Blistering can also be caused after construction of the hull if there has been damage that has caused micro cracks or separation of the different layers. In other words it is not always the builders fault. :)

    • @SteelDoesMyWill
      @SteelDoesMyWill 6 ปีที่แล้ว +2

      While improper application of Gelcoat is probably a huge factor, and as another viewer mentioned so is minor damage causing hairline cracking, the big picture to remember is that polyester based resins are not 'waterproof' at a microscopic level. Even the best isophthlaic gelcoat applied perfectly would eventually blister, but it would take decades. Epoxy is truly waterproof at a microscopic level, which is not only why epoxy barrier coast are used and why we use epoxy to repair blisters, but also why epoxy hulls are so much more expensive! Vinyl-ester resins are way better than polyester, but still not better than epoxy. Since Vinyl-ester resins are compatible with polyester in construction they are used as the outermost or 'first' laminate of the hull in the mold in higher quality yachts.

    • @JoshPostVlogs
      @JoshPostVlogs  6 ปีที่แล้ว +2

      Thanks, Sam! You are probably right. However, I've heard different opinions from different people. One guy who runs a boat repair place here in Annapolis told me not to go too deep or too big with my Dremel. But I have seen other advice also. I guess I will just see how well these hold up. They were fairly small. I just hope they don't come back anytime soon. Thanks for the comment.

    If you mix whatever type of fast-curing resin, move it to a wider, shallow container and spread the material to a thin layer, the heat within a large thick batch grows exponentially hence the smoking or 'flash-cure'.

  • @MrCaptbear42
    @MrCaptbear42 6 ปีที่แล้ว

    great video Josh! I had never seen using the cloth to repair the blister, but those were some large spots so better to err on the side of extra strength and a better repair than just patching it lightly. Time will tell.

  • @SkypowerwithKarl
    @SkypowerwithKarl 4 ปีที่แล้ว +2

    Many blisters will disappear shortly after haul out. Right after they pressure wash the hull, go around and pop and lift up the blisters with a small sharpened screw driver. This is so you can find them and to get them draining ASAP. The first chore after the boat is on the hard is to prep all the blisters since they take a while to dry. I like to give them at least a few days to dry if it’s not humid. I’ve used every thing from vacuum cleaners to heat guns to expedite the drying. Don’t use natured alcohol to dry/clean. Xylene or MEK is better but just two wet dabs, don’t soak it and do it about 15-20 minutes before you patch. I like to do wet brush of epoxy into the fiberglass to absorb right before the epoxy patch.

      Wow, you are very experienced with this! Thank you. I have a fresh water boat that is only 6 years old and was stored in a slip at the marina only during summer months. It has "chicken pox" so hundreds of tiny blisters, not big separated blisters like shown in this video. The gel coat shop said he can't fix it, they will just come back? And that I shouldn't worry about it now that the boat is no longer stored in the water. He says not to leave it in the water more than a few days. Do you have any insight into this? Thank you so much!

      @@garrettpeterson9816that’s the problem because you got a cheaply made boat… :(
      This is totally the manufacturer fault…try to get them sort the problem…
      These are the conditions for blistering:
      -water penetrates the gelcoat and antifauling;
      this is very hard to completely stop, it is said that it can only be slowed down because apparently even the epoxy is not completely waterproof (non porous) but alot more water resistant than polyester resin. To minimise this you can paint the whole hull with multiple coats of epoxy resin with 422 filler which further improves epoxy’s water resistance.
      -when water penetrates the paint it tries to find uncured polyester resin and voids between the laminate. When it finds them (this is the manufacturer blame) water starts to mix with uncured portions of the resin (and other solubles) and the osmosis begins in turn drawing more water and creating bigger pressure between layers of laminate in turn accelerating the blistering

    I’m a bit surprised to see the resin go off like that, it might be the quantity or that you didn’t get the base epoxy mixed properly before adding the filler (even though it surely didn’t look like that). Epoxy sets a lot faster in a pot compared to spread out though. For reference, I laminated a half square meter part at 22C yesterday, using the fast hardener and almost a kilogram of resin, and it took its time setting up, maybe an hour.
    Acetone is preferable for cleaning, as it flashes off almost instantly (in warm conditions it is almost impossible to trap any acetone as you’d have to be in humanely fast with applying the resin). The glass matting is probably a good idea, since it adds strength, where the filler doesn’t.
    Great video though, you’re really good at making interesting videos!

Wouid i repair these in the same way? Separately, i have noticed that the boat has been sitting low in the water since the haulout. Can water absorption be so so severe that this can occur (or do we have something else going on)?

    I find if I put the cup of thickened epoxy into another cup of ice, it will not kick as fast and you can complete the work in the hot sun.

    @snakeplisken4278 6 ปีที่แล้ว

    Interesting and make it seem less daunting. What type of Mat did you use? I have seen people cut various size disks of mat for larger areas, would you recommend that too? So no new barrier coat needed then...ie the epoxy layer is enough before bottom paint?

    • @JoshPostVlogs
      @JoshPostVlogs  6 ปีที่แล้ว

      I was thinking the same thing about the barrier coat, but I think the epoxy essentially acts as the new barrier coat. I just followed instructions I found at BoatUS.com. Not sure what type of fiberglass mat I used. It seems like a standard (mid-range) size. I just bought the stuff they had on the roll at the marine store. It's tricky to cut into a perfect circle though, so I just improvised. Thanks for the comment.

    • @snakeplisken4278
      @snakeplisken4278 6 ปีที่แล้ว

      Thanks again. Like the clear instructions you provide. What worries me most is having enough time for dry-out. Do you perhaps have advice / experience with installing/replacing a depth sounder thru hull fitting, specifically what the best sealant to use is. I have seen some people use silicone, but surely that is a bit risky? At the same time using 5200 might prevent future removal?

  • @en8581

    • @JoshPostVlogs
      @JoshPostVlogs  6 ปีที่แล้ว

      Thanks! I believe the previous owners did some good maintenance on the bottom of the boat throughout her life. However, the rudder had more of a moisture reading. Not sure exactly why.

    • @thomasritter3159
      @thomasritter3159 6 ปีที่แล้ว +1

      Elliott Bennett rudder was not casted as part of the hull. Check out my post above. I've built boats, repaired boats and lived in an area where there were several boat builders within 1 mile if each other. Two different methods to build fiberglass boats. The cold method is to build a frame, lay several layers of thin plywood or other wood onto frame then fiberglass -- then spray with gel coat. The mold method they wax the inside of the mold, spray with gel coat, while tacky spray the fiberglass for basic hull. When cured water is pumped into mold and the basic hull pops out. The hull is then moved to where the stingers are put into the hull and the build continues. Most rudder's for sailboats are made with the latter method. If in either one of those methods the weather is too damp, too cold or the gel coat not sticky blisters will appear later.

    • @flyingdutchman6984
      @flyingdutchman6984 6 ปีที่แล้ว

      It could be because of problems introduced during construction but most likely because the rudder is under a lot of stress which can cause micro cracks or separation of the different layers allowing the introduction of moisture.

    • @cawfeedawg
      @cawfeedawg 6 ปีที่แล้ว

      that addresses the actually blisters but not the water ingress that is causing them.. needs to have all paint and coatings stripped allowed to dry and a full barrier coating applied.

    Is it okay to use a heat gun or powerful hair dryer to speed up the drying process?

    • @JoshPostVlogs
      @JoshPostVlogs  6 ปีที่แล้ว +1

      Good question. I've never tried either option. A heat gun may be too hot and might melt other paint and material near the area. I use a hair dryer for lots of boat projects including to loosen hoses from barbed fittings, taking off old vinyl boat lettering, and more. Here is an article I just found. Read under the heading Controlling Epoxy’s Cure Time www.westsystem.com/instruction-2/epoxy-basics/epoxy-chemistry/

    • @flyingdutchman6984
      @flyingdutchman6984 6 ปีที่แล้ว

      I put rudders and other small pieces in a closet with a dehumidifier which dries them out fairly quickly. Obviously this wouldn't work for an entire sailboat. I would avoid using a heat gun as it may introduce more problems as Josh suggests.

    "Blisters" are what they call 'Fisheyes' in automotive caused by dirt or contamination stuck under the paint...thanks for the great video👍

    • @otallono
      @otallono 3 ปีที่แล้ว

      Blisters are air pockets that formed when the fiberglass was laid, if you don't find all of them they can show up later like in this video. (They were there all along) This is also in automotive when dealing with fiberglass bodies (corvettes, kitcars). A much bigger and different issue than imperfections in the paint.

    No boat has ever sank from blisters.
    Most likely the repair is more destructive than just leaving the blisters alone. Paint the bottom and move on.
    Blisters are like bumps on a golf ball that make the boat go faster.

  • @wdahlstrom

    The rudder is not built like the hull. That is why the hull has few/no blisters. The rudder is gel coated foam with a metal frame the connects to the rudder post and then to the steering (wheel or tiller). This video will be very instructive as he completely rebuilds a rudder with similar blistering. Take a look:
    th-cam.com/video/MRXNnFx7DBQ/w-d-xo.html
    I like Josh's videos but he is an amateur trying his best and making mistakes along the way. Don't act on Josh's example until you have read all of the posted comments. His previous hull transducer replacement video is a good example of what I mean. His methodology got the job done but was akin to "counting the cows by counting their feet and dividing by four" ie there is a better straightline method as pointed out by many posters. This isn't a criticism of Josh just a reminder that group knowledge often highlights a better way. And on his decision to keep the transducer astride the keel instead of forward of the keel as his manufacturer recommends. Modern depth sounders may not work well astride the keel. The new one may need a 360 degree, obstruction free signal cone.

    • @JoshPostVlogs
      @JoshPostVlogs  6 ปีที่แล้ว

      WD WD - Thank you for the comment. I am aware of that other rudder rebuild video by Andy at Boatworks. I saw it and researched how much that method would cost -- $6000 to $8000. I felt my rudder was in good shape aside from the relatively small amount of blisters. Also, I researched the depth finder keel issue and considered your rationale. My decision to place it as such was supported by the fact that it is forward on the keel enough that the keel is only present for about the first 12 inches down from the hull, then the slant aft causes no more keel underneath. I hope this means the depth cone will not hit interference. We shall she. I'm not an expert as you correctly pointed out. However, I did a lot of research. My blister repair was taken verbatim from a guide on boatus.com website by renowned sailor Don Casey. Since the days of Columbus and Magellan sailors have been doing boat repair projects with far inferior materials than we have today and somehow most sailors, if they have good common sense, end up fine, afloat, and ready to sail another day. But I honestly appreciate your feedback and I COMPLETELY agree that the group knowledge and insight from this site and other forums is invaluable. Cheers!

    • @wdahlstrom
      @wdahlstrom 6 ปีที่แล้ว

      Casey is the Best. I'm a bumbling sailor/maintainer well practiced at both after 40 years on the Bay. Maintaining and fixing is a much easier task with the help of TH-cam and content producers like you. Thank you. See you at Fawcetts.
