Best of luck with continuing good informative videos, and a speedy comfortable recovery with your upcoming surgery. Take your time Boots in need of attention. Will still be here once you’re back on your feet.🖖🏼
Surface contamination. Simple. Thanks for your efforts. I subscribed when I needed an understanding of epoxies/fiberglass/wood for a camper and motorcycle project. With those completed, I find myself learning something with each video. Thank you for adding to my knowledge base. Happy Easter.
I don't own any boats, but I work in a boatyard. I'm really digging this channel, it's cool to see how other professionals approach a problem and solve it. I'd like to add, depending on your barrier coat (240LT, Tuff-Stuff, etc.), it can be kind of finicky, especially if you're in temps below 70 Fahrenheit. He may have missed his chemical bond window when overcoating with itself or bottom paint.
It looked to me like there is a delamination issue between layers of Gelcoat and glass, probably caused by a bad layup at the factory for which epoxy might well be the answer. If the blisters are full of liquid then this is through water being drawn into the substrate by osmosis and reacting. The substrate needs to be dried out and the glycols removed which can be a very involved and lengthy process
Thanks for the videos. My friend has had the shoulder operation on both sides. Ten months to a year in between and to recuperate. She says they are Ninety some per cent now, a couple years out. She also doesn’t say anything about it unless asked now. Which is a good indicator of how she is feeling. Follow your doctor’s instructions, do all your exercises, don’t cut corners on yourself. Take care.
Good luck with your surgery Andy! Really like your format with fielding questions from DIYers. It would be good to follow up with gthem and have them submit a video of the work after they perform the repair andsee how they did. Just a thought to maybe expand on this a little. After looking at this boat issue it looked more like that boat is going through a little delamination issues. Im no boat expert but that looked bad.
I wish you the best with your surgery. I had my right shoulder done January '23. Mine was not as damaged as yours. You probably will not be catching up on sleep. It was very hard to get comfortable until I got out of the sling (6 weeks). Therapy worked wonders but it was not fun. I have full motion in both shoulders. Looking forward to you getting back to working on boats. One thing that has always bugged me is the light green smear on the bow of that beautiful blue hull that you use for a backdrop often times. Take care of yourself.
Good luck with the surgery. I had my right one done in 22' and it was all about the rehabilitation to get it back to 100% and that wasn't easy at 67yo. And i ain't looking back anytime soon.
All good techniques. Another Gremlin to look out for is permeable fibreglass. Oils, water seeping from inside the coarse glass hull are potentially contaminants. Also, cover the sanded hull between cleaning stages. Outside air blown contaminants in some environments, like auto exhaust.
Good luck with your surgery! Regarding the surface contamination, I would take an extra step and test the effectiveness of surface prep you describe. Clean the surface, sand, clean, apply a wash coat of epoxy, then a bulked layer, in a small area, a square foot or less. You could do a second sample area using the protocol you've used in the past, and additional samples if you have other things that might work. A different cleaner or sealer for example. Let the samples fully cure and see what the results are before committing to the full hull. Better to know for sure that you've corrected the adhesion problem before continuing.
Andy, the boat has been hit with penetrol, nothing will bond to it. Penetrol is a metal paint additive but in it's PDS it says it can be used to polish your fibreglass boat! Absolutely crazy recommendation. It's mineral oil based and absorbs deep in to the glass. The boat can't be fixed if this has happened. Same for boats that have been hit with lanolin oil. You'd have to grind out quarter inch to have a chance.
In the bass boat community we have a blister problem caused by water infiltration to the gel on boats. This was mostly effecting 2003-2010 era when the gel formula was changed. The gel coat with wet bunks and boat pressure cause the water to infiltrate the gel.
I had a very painful shoulder issue. They recommended surgery but I chose to go to a chiropractor who had me fixed in two months by manipulation of the shoulder to break up adhesions and restore the range of motion. Each session was followed by stretching, exercises, STIM and ultrasound. Shoulder is good now. Sounds like you have committed to surgery but I wanted to let you know that chiropractic can be a good option.
Hello Andy. I do not have a video-worthy question ! I have a late 60 glastron cv16. I am splitting the boat to do transom . My question is should I use plywood or liquid transom?
Really depends on how you approach the removal of the existing core. Personally I'm more of a fan for sheet material (ply, coosa, etc) but something like SeaCast if you're able to remove all the core from the top could also be a good option
From the video the guy sent it looks like the gelcote and laminate is potentially so wet that the Gelcoat is just peeling off , personally I would get a contact free moisture meter and check how dry the hull is ,epoxy will stick to pretty much anything except water
I'm making a Halloween prop cauldron and I am going to use polyester resin with 4inch biaxial tape and chopped strand mat over the top of a PVC yoga ball as a form. I will be using a wax release on the ball. Any advice for a newbie and I've never worked with fiberglass... I hope I don't burn the yoga ball before I have my shape. Nobody makes big cauldron props so I am stuck trying to fabricate my own.
I think the week is pretty well booked up with the project that we're working on, but sounds like there may be a chance of attending Newport again? Not sure about that though, details haven't been discussed yet :-)
Painting houses years ago TSP was great for washing interior walls and cabinets because it cleaned and chemically roughened surfaces. But, good ol' California banned it and it was replaced with something similar. Point being, TSP may be not available in all States. Something else I learned was that chemicals remove lots of stuff but in kitchens especially using dish-soap and water before the chemical cleaner was worth the extra time and effort. Soap and water dissolve some organic matter easily that chemicals have trouble with. One thing I'm having trouble understanding is if epoxy will adhere to polyester but an overcoat of polyester on epoxy won't adhere: under is ok but over isn't? BTW I just learned epoxy and polyurethane can be mixed. Fiberglassing is a complicated world.
That's what I don't understand: over or under, it's one against the other. How does it know it's over or under? After everything sets up and I turn the boat upside-down so that over becomes under, it won't stick? I'm kidding, but you get my point.@@boatworkstoday
I look at blisters like bumps on a golf ball, they make the boat go faster. Blisters do less damage than a guy with a grinder or worse a plainer. You get a better deal buying blisters and then you can pass on the savings when you sell. About your shoulder, make sure you don't end up with a frozen shoulder.
Water intrusion dissolves the resin and creates a larger molecule that generates the pressure that causes the molecule This schmoo is water soluble and will not allow resin to bond. over thick peanutbutter putty will not allow the bond zone to get "WET" enough kerosene space heater can also damage the bond
You’ll be lucky they give you asprin for pain. I was really busted up, they said buy Tylenol and maybe advil. Druggies ruined access to good stuff, doctors are terrified. .
What about drying the glass before beginning the repair, nothing sticks to wet glass......see osmosis treatment warrior 38, Sail Life......Mads used a heating pad and forced the glass to dry before starting the repair.

Thoughts and prayers for you and your medical team. Speedy recovery.
Hello Andy, wishing you a speedy recovery. It takes time to heal so try not to rush back to work. ❤
well speedy recovery to you Andy and thank you for all you do.
good luck with your surgery, mate. hope to see a fast recovery and many of your vids to come....

Love these type of videos. Learn so much. I would be really interested to hear a follow up on this one.

Like the new Total Boat hoodie! Bet you had a great week in Bristol!
Andy. How about drying out the area and checking moisture levels👍
Happy Easter Andy! Maybe I’ll se around town next week. Great video. I’ll buy you a beer at Aidan’s.

Could water/moisture be coming inthrough from the inside of the boat?

Best of luck on the shoulder surgery.
Hi, Andy. Will you be making any appearances while you're in RI? I was hoping to see you at the Newport Boat Show, but I missed you.
I think the week is pretty well booked up with the project that we're working on, but sounds like there may be a chance of attending Newport again? Not sure about that though, details haven't been discussed yet :-)
Don’t try much till you’re feeling up to it. I once tried answering emails too soon and my responses were, well, lacking

Yup, epoxy pretty bonds to everything :-) It's poly that shouldn't really go overtop of epoxy
That's what I don't understand: over or under, it's one against the other. How does it know it's over or under? After everything sets up and I turn the boat upside-down so that over becomes under, it won't stick? I'm kidding, but you get my point.@@boatworkstoday
@@choimdachoim9491 polyester resin is like paint if you have a choice between poly or paint chose paint
It's not over or under but what was cured before....
I look at blisters like bumps on a golf ball, they make the boat go faster.

This schmoo is water soluble and will not allow resin to bond.
over thick peanutbutter putty will not allow the bond zone to get "WET" enough
kerosene space heater can also damage the bond
220 grit. Epoxy primer. Then have at it.
You’ll be lucky they give you asprin for pain. I was really busted up, they said buy Tylenol and maybe advil. Druggies ruined access to good stuff, doctors are terrified. .
"B" for Beneteau lol. I can't believe a Beneteau is actually blistering like that...
