Help with paint, and transom repair question

[cmiddl01]

OK so you guys have seen this boat a couple of times now.

The paint question if you look at the picture. you see a clear coat like pealing. is there a cheep way to get this looking nice. My wife loves the color just want it to look shiny and nice again.

the transom question if you look at the two pictures you can see that it needs to be replaced. the stingers are solid. and the pictures look worse then what it was when i got it. due to me starting to tear it apart. as you can see the cap comes down over the transom wood. is there a way i can do this without poping the cap off. I really don't want to do that due to this being my first boat, and i am very armature when it comes to fixing the hull. should i just cut out a 2 inch section on the cap and fiberglass it back in? sorry about the quality of the picture made me re size them

Re: Help with paint, and transom repair question

If you are going to install two or more layers of plywood in the transom, then you can cut each layer into two pieces being sure to stagger the seam area where you cut in half. Try to make the cuts towards the port and starboard sides, and not in the center. Be sure to use epoxy for your transom rebuild, and after replacing plywood, wet in a couple layers of 12oz biaxial fiberglass cloth with epoxy, extending fiberglass 4" to 6" on the interior sides and bottom.
Make sure interior transom surface is clean, dry, and rough sanded before epoxying plywood in. You will need to either clamp, screw, brace, etc., plywood to interior transom, being sure to make a tight bond.
Below is a link to a transom rebuild I am almost finished with to my 22' Grady White. Although it is a different type of boat, it will give you the basic program to doing a transom rebuild. Hope this helps, Mike.

Re: Help with paint, and transom repair question

I cut the cap off my transom with a sawzall then I removed the rotten wood with a long drill bit and a chain saw. I used SeaCast to rebuild the transom because I couldn't bring myself to put wood back in there. After I got the transom back in, I put the cap back on with some fiberglass cloth and polyester resin in between. I'm an amateur and the job could have looked better but I can only see a couple cuts.

Re: Help with paint, and transom repair question

OK thank you for that link on the transom. I feel more secure in doing it. I looked into the seacast aswell but for the boat it would cost way to much. so I am going the wood way.

Any ideas on the paint. it looks like the clear coat is just flaking off. is that what it is. is the green the gel coat? can i just pick up a can of polyurethane clear coat. and sand it down and re coat it?

Re: Help with paint, and transom repair question

I'm not sure what finish is on your boat at the present, but it doesn't sound like everyday gelcoat. I'm sure someone will be along with more knowledge than myself on this.
Regarding the "Seacast" method of repairing transom, that is what I originally planned on using. I thoroughly researched this method, and searched prior users, etc.. One thing I read more than a few times was that this type of repair was very brittle, and susceptible to cracking and shattering, if lower unit strikes a hard object, or if bumped into dock, etc., hard. Let me make this clear, this is only information I found while researching this type of transom repair, and is not something I have witnessed or experienced firsthand.
There are other materials other than wood to use for transom rebuild. There are foam-type products, and other starboard-type products among others.
As far as my repair, it will be impossible for any water to get to the wood used in the transom, unless someone actually drills through or removes the epoxied multi-layers of fiberglass that encapsulates it. Any area that needs to be drilled for attaching screws will be first drilled out at a larger diameter, filled with an epoxy and fiberglass flour paste, and then the smaller hole for attaching screw will be drilled. This will completely encompass all attaching points with epoxy/fiberglass.
This being said, I can see no reason why this transom would not last indefinitly. JMO, Mike.

Re: Help with paint, and transom repair question

It may be everyday gel coat not sure. I got this boat from a junkyard. I had to rip everything out of it. The person that had it had wires and everything everywhere. They may have just through some polyurethane over the gel coat, not sure. I got the transom wood out last night and boy oh boy was it wet and soft. when i get home I will see if i can post a picture of it. and I have another question that will be better explained with a picture.

Re: Help with paint, and transom repair question

vero,
Nice job on your transom,
Im going to start mine today I have a post on here with pictures what size plywood did you use? and did you use a glue on each layer or epoxy between each sheet? what did you use on the first peice to secure to the outside Glass? could you give me a shopping list? Thanks

Re: Help with paint, and transom repair question

Thanks for the link...good work, nice progress on your rebuild. Keep updating your site as you go along...the whole thing would make a good "sticky" thread in the Iboats restoration forum. Rebuilding/replacing a transom in a f-glass boat is way more work that I encounter when I refit a tinny...hats off to you sir.

Re: Help with paint, and transom repair question

LOL i just got the old wood out so far. haven't got to put the wood back in yet. got to get a little more funds to get the wood. this is going to be a over the winter project. but there is a lot of guys out there that can tell you what you can use. I am not sure exactly yet. I have heard a lot of people talk about an epoxy and clamping or screwing everything together till it cures. not sure what epoxy yet. have fun and I would like to see your project.

Re: Help with paint, and transom repair question

I don't want to hijack cmiddl01s thread, so I will start another thread on this transom rebuild.
I will tell you however, that I used 4 layers of 1/2" Meranti BS 6566 plywood. I used ONLY Marinepoxy for all glueing, attaching, filling, etc., and that includes attaching first layer of plywood to interior transom fiberglass. There is nothing better. Epoxy is much better than what was used(Vinylester-type products) on original boat. I used a 12oz biaxial 6" wide fiberglass tape on all corners and joints (4 staggered layers), and 12oz biaxial cloth on the finished inside transom (4 layers). Thats pretty much it, as far as material.
A couple of key things I can tell you are, be sure to epoxycoat every single square inch of every piece of wood that you use, especially the edges. When adding plywood layers to transom, mix in wood flour to thicken epoxy to a ketchup-like consistency. Then trowel this mixture to the face of plywood being installed and face of interior transom or previous installed plywood layer. I used an 1/8"-3/16" trowel. Be sure to clamp, screw, brace, etc., each piece solidly and completely to transom, with no air pockets or voids. That is key to a good solid transom.
Last, but not least, after all wood is installed, completely wet in at least a few layers of fiberglass cloth, completely encapsulating all wood. This is what will keep it dry and strong for a long time.
Good luck on your transom rebuilds, and feel free to PM me if you need any more info. Mike

Re: Help with paint, and transom repair question

You didn't hijack this post at all I appreciate all the help i can get. this is my first boat/repair job. I am glad you told me to use marine epoxy. I want to do this right the first time. I want to use this boat for a year or two then sell and move to a bigger boat. How can i tell what fiberglass my shop has.(machining shop) its on a 3 foot long roll here. the owner said i can use as much as I want. the fibers are woven on 45 degree angles to each other and actually seems pretty heavy.

Is there a special resin i need they have this here. it says:

Polyester Resin​

Ashland FRP
FRP A-101-T-15
UN 1866​

It uses organic peroxide as the hardener. and we have silica for the thickener.
will silica work just as good as wood flour? I never heard of wood flour before.


My shop just moved into this building and I almost have everything cleaned up here to be able to bring my boat in and work on it during lunch time and after work.

Any ideas on how to clean up this bubbling clear coat without hurting the green what ever kind of paint that is?(its what it looks like to me.) see the 2nd picture in my original post.

Here is a couple of pictures of the boat i am working on encase you guys are wondering.

Re: Help with paint, and transom repair question

just after I posted i came across this. I think it would work very well for someone that doesnt have a lot of money to put into a boat. but would like to get it looking good.

This would be for the top side atleast what i would use it for.

Re: Help with paint, and transom repair question

The marinepoxy is used instead of the Polyester Resin. Marinepoxy is superior to polyester Resin, but actually polyester resin is what is used when most boats are newly built, to the best of my knowledge.
As far as which fiberglass you have at your shop, try to find out what they are buying, or maybe cut a piece and show it to someone that can identify it.
I know, for myself, if I could get all the fiberglass cloth and the Polyester Resin for free, I would definitly use it instead of buying marinepoxy.
I do recall when researching my project that some resins do not adhere properly to fiberglass materials, and surfaces, but I am far from a pro on which they would be.
If you can not get any answers locally, or here, you can check the forum link below. This is where I found most of my info for my project, and you can find any and all info you need there from buiding a boat from scratch, to any type of repair and materials to use. I have no relationship with this place, other than getting info from their forum, and purchasing material for my build from them. I just found them very helpful. Mike
