Best way to fix leaky carbon a/m hull?

[Quinc]

Have a bob gen3 with a bunch of spots that the carbon did not fully wet out and now that the gel coat is wearing she is starting to leak. My plan is to put a layer of glass throughout the entire hull. Since I am only doing this for leaks and not structure what is the best option?
4-oz s-glass?
1.5-oz chopped mat?
Never wet?

Couple cans of flex seal. If they seal a screen door on the bottom of an aluminum boat you should be cherry lol

S glass is real nice to work with.

Did you call the builder and get his suggestions? Chances are if your hull did not wet out, nether did the others so you probably won't be the first one and a fix has allready been figured out. Just my .02

And if that does not work you know what they say about duck tape. If you can't duck it...

Gorilla tape works amazing on skis.. You'd be surprised.

I hope that's a joke lol

I taped off front hood vents and old hood hook holes and it's lasted for two seasons lol

I taped off my hood vents at the ocean for a weekend with blue painters tape and it lasted. I called the ski clinic and talked to there glass guy and he recommend 1.5oz mat. But hoping to hear from people who have done it and what there results where.

To expensive and not enough benefit.

Wait... Their glass guy recommended you lay down chopped mat to fix a production problem where they didn't fully wet out the carbon? Am I the only one who thinks that sounds crazy? What resin did he recommend that you use?

Do you have any pictures of these areas?

If you need to lay down glass to repair a previous layup that was not fully wet out then you certainly should be performing a structural repair and not just sealing it up.

I don't mean to sound like a dick in that previous post, I am just surprised that a) they aren't taking care of a production issue, and b) the recommendation was to use chopped mat to "seal" dry fabric. Pictures and the size of these dry areas would help us understand the extent of the issue, but I agree with what MikeyB said. And even if these are very small areas, I wouldn't seal them with chopped mat. Especially not chopped mat and epoxy.

Is the fabric completely dry or does it look like it just wasn't fully saturated?

Yes, and two part epoxy.

The ski is 3ish years old and has been ridden hard and overall seems structurally fine. The dry spots look dry like you can scratch at them with your finger nail and pull part the carbon fibers apart. Also there are no cracks or anything around them but you can see water slowing seeping out of the ski when you fill the engine bay up with water. If not chopped mat, should I go with S-glass, or?

They are small spots in the engine bay and I am sure there are more under the tray.

The ski is ride able, but what is the point of having a light weight carbon hull if it takes on gallons of water.

ahh I was guessing it would have been in sharp corners or something. Wonder why spots in the middle of a flat piece were not able to wet out? Did they say?

 

[chucktor]

Quit being a cheapo and get crazy with some carbon!

Talking to other people with ski clinic skis it looks like it is a normal part of the process.

 

[Nate_D]

It's not. Regardless if this ski has been ridden hard for 3 years or fresh out of the shop, dry fabric is a manufacturing defect.
