I'm starting into the restoration of a Formula 233, I've got so many great tips from this video. Keep up the good work.
Glad to help! Thanks for watching!
thank you for the emphasis on the CSM non compatibility with Epoxy, great introduction video IMHO
You are welcome! Appreciate you watching!
Great info on the different types and the best application to be used in.
Glad it was helpful! Thanks for the comment
Very informative as usual, Im learning loads thanks
Glad to hear it!
Mind blown. Can't thank you enough for sharing this valuable knowledge. I'm restoring a 45' south african power cat. Needs some fiberglass work, and out where I'm at, there's no one do do it unless you want to pull it out of the water and let it sit out of service for months. Now I feel confident taking on some of the small work that needs to be done.
Glad the videos are helpful! Best of luck with your project
Excellent video! Thanks for sharing your knowledge on fiberglassing for boats, exactly what I was looking for.
Glad it was helpful! Thanks for watching and commenting!
Really excellent overview on materials and just as importantly, when you would use each one.
Thanks so much, I appreciate the comment!
Particularly useful to know about CSM and epoxy, thanks
Glad to help!
Awesome info ! Thanks!
Glad it was helpful!
In this area, they call the CSM matt "angel hair" and the roven woven "matt". Only other thing they use is "chopped glass" which everyone seems to hate. Funny how you get colloquial terms in different areas.
That's interesting! Thanks for sharing and thanks for watching!
Thanks for this valuable info 🙏
Glad it was helpful!
Thanks for all your videos. I've been binge watching. I'm currently doing a restoration on a 24 foot Morgan. It had a yanmar diesel in it and I'm converting to an outboard. It's a lot of work. Your videos definitely inspire me. Thanks again. One Tip that I have learned. Use your little acetone bottle. Draw a line with acetone and it rips really easy on mat
You are very welcome, sounds like a very cool project! Yes, the acetone melts the binders in the mat. that is a neat trick. thanks for sharing!
Great job thanks
Thank you too! I appreciate you watching!
I love you videos i keep learning just in case one day i need to know lol
Thats awesome! Thanks!
Thanks again for another tip on pulling the mat against a straight edge to feather the edge. I always cut and pulled to feather the edge. Not any more .Thanks
Glad to help!
I have so much to learn
Glad you are finding the videos interesting, thanks for watching!
Great video.
Thank you!
Grear diy intell thx
Thanks! Glad to help!
This is great information. I want to build up the inside of my center console cause its too thin to mount any new electronics to and I want to redo all the wiring and want to design build my wiring since I am an electrician by trade. Was thinking plywood but I'm more leaning towards glassing in some coosa board instead.
Glad it was helpful! Coosa works great for what you are wanting to do, but plywood could also work. Thanks for watching!
Capt Joe appreciate y'all sharing these products was also hoping for a video with a more in depth mixing MEKP simplifying the process so everyone can achieve great finish results this process not to waste material and time Thanks fish bump family!
Glad you are enjoying the videos! That's a great suggestion, I will try to do something along that line soon. Appreciate you watching and commenting!
Another informative video Capt.
Electric scissors are the best addition to the industry in 30 years. another related suggestion is if ya'll's scissors get dull you can sharpen them very easily.
Thanks again Capt Joe I’m interested in the electric cutter didn’t see it in notes , brand & model I’ve got a small battery 1 it works well but to small, I enjoy working on boats as a hobby not job helping a friend restr. 73 seacraft & after that a73-19’ mako total restoration (my dad’s) thanks again for sharing 👍👍
It is a Romech brand, I bought it on amazon. Sounds like some great project boats. Always been a fan of the seacrafts! I appreciate you watching!
Great video. Which would you recommend for building a swim platform? And do I need wood or can it just be multiple layers of fiberglass?
Great information. I'm getting ready to do some small boat repairs. What about information on the weights of the different CSM? 1 Oz or 1.5 Oz and when to use either. Thank you so much for the great information you provide.
Thanks! 1oz is just easier to wet out because it is thinner material than 1.5 oz. They make 3/4 Oz, but I find it to be somewhat delicate to handle. Just remember that csm doesn't work well with epoxy resins. Polyester and vinyl Ester are fine with csm. Hope this helps, thanks for watching!
Nice and concise Capitan! A follow up video would be appreciated:
How do you come up with a layup schedule? How thick is a layer of cloth? Do you always do mat first and last, or is it not needed first with the xx08 fabrics? i.e. 1.5 oz mat - 1708 - 1808 - 1708 -1.5oz mat? Mat matters more for visual finished surface, or is it needed to hold extra resin for a good bond (or both)?
How do you estimate how much material to buy? is there an waste percentage that is common, 10%?
How much resin/yard would you estimate?
How many layers can do in a single layup?
How do you decide to have a core vs solid glass?
Thanks, all great suggestions! I will try to add some or all of those to a video. I appreciate you watching
Thanks for the great videos. Keep them up I’m not working on a boat I’m working on car parts. Wondering how you do sharp edges like on a fender or a hood when it comes to the edge how do you get them to the bond together or never done it like to know, thanks again
Glad you are enjoying the videos! I have done some body work on cars and trucks in the past, but boats are obviously our main area of expertise. If I understand you correctly, I would feather or transition the glass as you get to the edges or seams of the fender or hood. If it is a body line, or crease you may have to use a premium body filler or putty to get the shape you need. I will try to do a video on body work and fairing out glass soon. Hope this helps, thanks for watching!
I've never done any fiberglass work or anything remotely close and I'm undertaking a resto job on my 27' 93 chaparral cabin, so I'm studying these videos 😅
I hope the videos help with your chaparral resto! Best of luck with your project!
Great videos! Love the content. Thanks for sharing your knowledge with the world.
Question. Can you use polyester resin with 1708? I am trying to purchase one resin that will work with CSM and 1708. Thanks!
Yes, polyester, vinyl Ester and epoxy will work with 1708. Csm does not work well will epoxy. Thanks, glad you are enjoying the videos!
Thanks for the quick reply!
@@countryman02 Your welcome
Capt joe, I see in your videos you lay up your coosa with alot of vinyl Esther resin and you run 1708 by axial and finish it off with CSM is that because your CSM does not have styrene bonding in it ?
Hey man...I love your videos.
What gets confusing for us non- Americans is your number system.. 1708...is the 0 a zero or an "owe"
Thanks! Sorry for the confusion. It would be 1708, not owe 8. We appreciate all of our viewers, and I am working on adding more metric measurements and easier to understand pronunciations for everyone. It is a work in progress for sure!
Very informative, thank you!
Glad it was helpful! Thanks for watching!
Thanks for the great videos!
I’m about to start repairing a hole on my 1976 Fairline Phantom 32.
May I ask if standard mat and woven roving will be sufficient for the job?
Or should I use some biaxial fabric like you did on your repair video?
The damage on my boat looks similar and might be a through hole.
If the standard mat and woven roving is sufficient, what thickness should I buy regarding woven roving?
Glad you are enjoying the videos! Yes, you can use mat and woven roven instead of 1708 if you prefer. Just remember to always start and finish with mat. It bonds better on the first layer than roven, and has better cosmetics on the last coat. I like 18 Oz roven personally. I hope this helps and thanks for watching!
@@FishBumpTV Many Thanks! 😊👍⭐
Thanks again.
How is it that the chop stran mat form Europe is made so epoxy will work. Will we ever get that . Puzzling? Thank again
It has a different binder in it that is designed to work well with epoxy. It seems crazy that it is not available here in the States, or at least I haven't found a source for it. Thanks for watching!
Which one would you use for difficult shapes like the rounded corner of a heelcup? Does the extra thin mat wrap around those areas or should I cut several overlapping shapes?
And what might be a good pressure if I do a positive and a negative mould and press the fiber together?
The mat works very good around difficult shapes when used with polyester or vinyl Ester resins. The light weight finishing cloth works well with epoxy around difficult shapes. I don't every use two part molds, so I don't have a answer for that one. Hope this helps and thanks for watching!
How many layers of 1708 would it take for a say 16 to 20 foot skiff style hull. ?? Thanks
great video
i have quesyion please
i have crack on the floor of the bath
i bought Bondo fiberglass resin repair kit does it ok?
Thanks! I don't use much of the bondo brand resins, and resins can vary a good bit in what they can do. It is possible it could work well, but it is hard to say for sure. Wish I could help more.
understand CSM not working with epoxy, Question, can you use epoxy as a second layer after glassing with laminating resin? will epoxy adhere over the resin once you apply the second layer of, say of 1708. Great videos.
In most cases yes, you can put epoxy over polyester without problems. Hope this helps, thanks for watching!
thank you for the info, greatly appreciated.@@FishBumpTV
Great content. Which glass is lightest? Curious
Thanks! The 6 oz finishing clothe is the thinnest and lightest.
Thank you
question, is there a version of mat that does work with epoxy?
because i really like the way you use the mat to feather out and hide the edges of the roving and the 1708 on the other vids where you showed how to fiberglass plywood, but i was wanting to use epoxy for a project i'm planning
Yes, stitched chopped strand mat is compatible with epoxy because it uses no binders.
@@WereAllThatBored awesome, thanks for the info
There are also csm
Make more videos please!
You got it!
I am doing a complete overhaul on a 1996 angler center console. I have replaced everything with coosa board. I am now doing the floor and I have 2 pieces that are 1/2" thick woth off set joints nonetheless floor. I have 1 layer of 1808 down now and it feels solid. Should I put another layer of 1808 down then glass the console in or just glass the console in ?
Every boat project is different, but we usually go on the heavy duty side when doing glass work. When in doubt we usually add another layer. I hope this helps and best of luck with your project!
Surface veil works also or 1/2 once matt
Thanks!
Hello Joe, I’m restoring a 1973 VIP Bay Stealth. Do I need to remove all the gelcoat in the hull, before laying in new glass? Or can I do a rough sanding and lay in the glass?
I usually recommend removing all of the gelcoat and get down to solid fiberglass. I usually use a 24 grit sanding disc to put a very aggressive tooth or surface on the original fiberglass so that the new fiberglass can bond better. I hope this helps and thanks for watching!
Tearing the Matte is the same principle as finish drywall or using body filler and even spray painting.. We call it feathering out the edges. Tearing the matte creates the feathering effect when transitioning to another surface. It can reduce or even remove the visual layer change.
Yes, it really helps the quality of the finish work. I appreciate the comment!
That and staggering layers to avoid thick spots
very informative. now I know as to CSM, just tear the mat. now how will you do it as to woven roving sir? please, thank you.
Thanks, you can stagger the layers of roven or biaxial for a smoother transition. Hope this helps!
I have a 89 celebrity that has cracks in the strakes and was wondering what you suggest using to repair the cracks. They are leaking water into my boat. Thank you
That could be a serious structural problem and might require some serious fiberglass repair work. Most damage on boats could be considered cosmetic, but if it is leaking water into the hull, that would be structural damage. We have not done any videos on that kind of repair work, and it might be something you should talk to a repair shop about. At least see what they would have to say. Hope this helps and thanks for watching
Which one will you recommend for automotive applications
The csm or chopped strand mat is a good all around glass for automotive work. Hope this helps and thanks for watching!
Thank you very much
How do you determine a fiberglass layup schedule?
It varies from boat to boat. Large boats require more glass than small ones. Commercial work boats are usually built heavier than pleasure boats. So there are many factors. Also just plain experience working with many boat of different sizes you get to see what works. Our 29 ft custom charter boat we built has 2 layers of 1.5 Oz csm for a skin coat, then 10 layers of biaxial on the hull bottom. That yields around a 1/2 inch thick laminate on all flat panels. Nearly 1 inch where it laps in the keel and chines. Hope this helps, thanks for watching!
Where do you get the fiberglass roll tower?
We built it in our shop years ago. It really makes it easier to work with glass. Thanks for watching!
You never stated why chop & strand mat isn't used with epoxy and what is used for it. Can you please elaborate? Also what's the diff btwn epoxy and poly? (I hate watching vids that are abreviated and leave holes in knowledge). This is complicated. So mat works with woven roven and then can accept epoxy? There are a lot of nuiances here. Thanks!
Pertinent comment re random weave.
Thanks for watching!
您好。我是一个中国工厂工人长期接触玻璃纤维布。加树脂胶。请问在您的国家玻璃纤维对肺部有伤害吗？在我这个行业流传一个说法玻璃纤维和石棉一样。吸入玻璃纤维丝。会永久伤害人们的肺部!
why not mat with epoxy ?????????
Mat has binders that break down with the solvents in Polyester. Epoxy does not break the binders down. If you want to use epoxy with mat, buy stitched CSM.
Yes, that is exactly right! Thanks!
I bet that new stuff gets pricy
Yep, seems like everything is pricey these days. I miss the good Ole days!
