Hull Repair, should I attempt

[Texfisherman]

Hello all.

I have been reading and learning a lot from you all. So let me say thanks first.

Here is my problem. I have several chips taken out of the hull on the transom. The worst one is on the corner at the bottom of transom and continues onto the bottom. I couple on the corners I feel pretty comfortable tackling myself. But the larger one I am not sure about doing myself. Take a look at the pics I took and let me know what you all think.

Thanks

Re: Hull Repair, should I attempt

lol.....just a iboats joke....


the holes are no problem.....see them all the time......

most are gellcoat repairs....

for the one at the transom.....no problem either.....
grind the area till you are at glass.

i would mix up some peanut butter (search it here at iboats) and fill the area....then add 2 layers of csm on top of the area
then kinda sand that till its semi smooth...add a little gellcoat paste....then fair and buff....

after you do the others...this will be really easy

Thanks for the welcome.

When you say grind, should I be opening the area up with a dremel and cut wheel or just sand until I get all the odd edges out? Should I have rectangle or other regular shape when I am done grinding.

Rivets....Wow I was lost. If it was metal this would not be a problem.

Thanks again

A Random Orbit Sander or 4 1/2" grinder with a backup pad and 40 grit paper will make short work of it. Feather it all back 3-4" all around the large areas. The small ones, your dremel will suffice. Peanut butter is thickened resin using a product called cabosil and milled fiberglass strands or fibers. Mix it all up till it's the thickness of creamy peanut butter and spread it over the areas. Make sure to wash everything first with Acetone. Leave the patch a little low, then apply two layers of resin and 1.5 oz CSM (Chopped Stran Mat) Sand it smooth and either gelcoat it or paint it.

Re: Hull Repair, should I attempt

Which one is the larger one?

That hull layup does not look so good; those seem to be from air pockets left under the fiberglass mat.

They all look straight forward to fix. You should feel enpowered to fix all of them. Gelcoat patch kit in hand, but you might need a bit more gelcoat than what comes with the kits normally. You can buy white gelcoat in pints or quarts as well.

Re: Hull Repair, should I attempt

The first pic is the bad one to me. Located on the corner of the bottom to the transom. I thought the same thing about air pockets. Seems as though there was a void behind a couple of them. The others are from contact with rocks or stumps. I am going to start with the small ones first and see how it goes.

Re: Hull Repair, should I attempt

The resin from the Home Stores has wax in it so you have to do all the layups before the previous ones dry. If not you neet to sand with 60 grit between layers to get good adhesion between the layers. If you can find Marine Bondo Hair that is waterproof you can use it for filling. Not as good as making your own but it will work. the mat sold at the home stores is usually .75 oz so you will need more layers.

....he decoded the inside joke pretty quickly....impressive. May want to hide this little comment from our metal boat friends before it becomes their new slogan.


Welcome to boats. Wood and oops are two of the best glass guys on this board. Follow their advice and your boat will be better than new.

Didn't mean to slight anyone... forgot to mention there a few helpful "pros" (like YD) that hand out lots of advice as well. Ignore my gaffe...just trying to be nice...carry on, please.

No worries m8 ..

Ok.. now on to the project at hand ..

Tex .. You have some serious Air voids going on with this boat ..

Yea .. those chips you see are normal "chip it and fix it repairs" ( I always spray gel over below the waterline repairs though .. and very few repairs do I just Patch Paste and buff ).

You have Air Voids. .. lots of them .. by the time you can take a stir stick across your radius's your probably going to pop a bunch of them.

Call it a first time glass guy that got hired at that time .. or someone on the skin coat that didnt care ..or newbie at the lam rollout on that particular hull ..

You have air voids that should not be there. Not with a skilled crew ( that can change overnight trust me ).

Im sure you can chase those voids with a die grinder all the way around your boat. You can pop them now .. or pop them later.

Sorry bout your bad luck on your build ..

YD.

PS. I cant say how to repair at this point without more information .. Most look like simple gel repairs though ..

Re: Hull Repair, should I attempt

Holy carp. Glad I did not start anything.

When i saw the chip I was wondering about the gap between fiberglass and exterior. Should have read a little more before buying. It is what it is.

I am sure that these are not the only places I have problems, but I will address these and deal w/ others as they arise, or money and time provide. This is a fishing boat only. I want to make sound repairs but not rebuild the boat.

Thanks for the input so far.

YD what more info would you need? Trying to see the big pic here.

Re: Hull Repair, should I attempt

You need to get the boat off the trailer first off.

That first pic is going to need some lamination ( see post #3 ).

The only difference is that I would pack the large void with Mohair ( tiger hair ) glass filler first..then grind/bevel then layup glass. This way you kinda sorta still keep the shape.

You need to die grind the air voids and chips .. then fill with glass filler ( put a tad of white gel in there to get a better white base color for your final topcoat ).

Extream caution should be used when die grinding air voids. Yes you should be wearing safety glasses when die grinding .. but with voids its Especially Important ! You can flick a large chunk of gelcoat right into your peepers .. not dust .. CHUNKS .. ( you will know what I mean when it hits your forhead or your hand ).

Get the boat off the trailer .. do a little bit of grinding and post up some pics. We can go from there .

YD.

Re: Hull Repair, should I attempt

Thanks for all the info. I am trying to track down the supplies locally before I start tearing anything up. Getting the boat off the trailer is going to be a task, but I figured that is what I was going to have to do. Hopefully I will have all my supplies by next weekend and can get started. I will definitely be posting pics and asking for opinions.

Watch this and you will get the rivets joke.

Re: Hull Repair, should I attempt

OK I have been doing my research trying to find some of this stuff locally w/ not a lot of luck. I know I am not looking in the right place or asking the right questions. What I have found has raised some more questions.

I found resin and hardener #300 Resin and #21 Non blushing Cycloaliphatic hardener. Is this the right stuff?

Gel coat w/ wax of w/o?

Gel coat, should I look to be spraying it on or rolling it on? Spraying seems easier if you have the means.

Tiger hair I found locally but I can buy the ingredients to make peanut butter cheaper. I am sure this is one of those preference things. But is 1 really any better?

I know these are a lot of newbie questions but only one way to learn.

If anybody around Dallas, Tx and knows where I can buy all this stuff locally let me know. I know it is here local just not finding it.

Thanks

Re: Hull Repair, should I attempt

find shrimp boats and you'll find the supplies you need. kinda like truckers need deisel fuel. i live near the beach. found what i needed near the beach. most likely worth the drive. be leery of resin from a 55 gal drum. usually not fresh.
