JB Weld Epoxy for chip/gouge?

Genius buddy of mine was close to shore and was trying to show off his new moves - drove right on top of a layer of rocks nearly missing the edge of the dock by a few inches.

Luckily the damage isn't bad - scuffs that can be polished out, but 2 nice gouges that I need to fill.

I've done some searching, but I'm not sure how far down its gotten. It's white, so I'm assuming I've hit the Fiberglass? Can I epoxy right over it with JB weld?

It looks to me that it's through the gel cote and into the fiberglass, probably needs more than JB Weld, since it's new get a professional to look at it.

I'd take it somewhere....................and sock your buddy with the bill. My friendship would seriously be on the line. But, if any of my buddies did that, before they even got off they would say they pay for the repairs.
 
It makes me cringe to see that! i would defiantly take it to a pro to repair being a brand new ski and make him pay for it.
Id be boiling mad if that happened to my ski, but i am very anal and my ski will never be beached and no one will ever ride it but my wife.
just a piece of advice, if there is a next time i would highly recommend who ever rides it, that you educate them of the safety and rules and that it is against the law to play around like that, that close to shore and the dock! most places have no wake within a 100 ft from shore , dock or vessel. if a marine officer would have caught that there would have been a fine. and worse someone could have been seriously hurt.
I don't mean to sound harsh, just trying to give you sound advice.
Good luck and hope you get her fixed soon!:) post some pics when you get it fixed.
 
There is just to much there for an easy at home fix. I'd take it to an auto shop.

This make me wonder if a Spark model could survive being driven onto the rocks while "jumping the spit". Your friend has earned the "Bullet head" moniker! :)

But this ski looks like it's been on the rocks more than once, to me.

Anyway, JB Weld would make a decent gouge filler, I prefer Marine-Tex myself but either will be fine and I've used both myself. A thin plastic film cut from, say soda bottles for instance, can be used to smooth and level the filler while curing standard sanding smooth then I'd respray a color coat using epoxy appliance paint. Maybe you can get gloss black, I don't know.

But that's me, others might not agree.

Nothing wrong with taking it to an autobody shop IMO, those guys are good.
 
Oh I was definitely pissed off, and I appreciate the advice!!

It looks a lot worse than it really is ( I think) - majority of those are scuffs that can be polished right out. I did a quick attempt at compounding and it's already looking better. Gel coat has surface Scuffs.

Should I still bring it in to a shop, or should i JB WELD and wait until the end of the season to have it done ? It's hard to judge from the pics because of the shine, but I believe it's just the gel coat that's all scuffed up.

* Pics after the compounding - will do another compound, polish and wax after.

I think if you intend to have a shop repair the finish, you should not apply any filler that might be incompatible with the system they decide choose to use.

Meanwhile, you may buff or simply leaving it alone will do no harm.
 
Hot, doesn't begin to describe my mood if it'd been mine.

Personally, given the location of the damage....I would'nt be comfortable with a home repair. I've seen way too many pics of ski's suffering de-lamination.

I think you may be referring to the foam core, right? I agree, you may have a valid point.

They're built much like a surfboard, where the resined glass cloth is laminated to a foam core thus impact crushes the core and the damage results in delamination.
 
Brought it in today to a restoration specialist - they quoted me $480 CAD for a complete restore, but he also mentioned that he didn't think it would be an issue if I used JB WELD for the time being. He said to only go through with the restoration if I was sick of looking at the scuffs, otherwise if the epoxy is done right it shouldn't be an issue.

I also beach the ski when launching solo, so the gelcoat it bound to scuff up either way.

Most of you have suggested I have it fixed, but they've convinced me that running it the way it is with the epoxy will be OK.

That being said, If I go ahead and epoxy, what's the best way to sand (what grit) and blend it in? Do I need to paint it or that only for aesthetics purposes (no paint such that if I do the restoration it's easier on them)? The damage is all at the very bottom of the hull so almost unnoticeable unless you get under.
 
Your second set of pictures look MUCH better,,,

As long as there isn't delamination, which I am not seeing any, then the at home fix will work.
 
I'm not sure I understand the "de-lamination" concept - is that simply the loss of the gloss/shine that the hull has? On the areas where the scuffs are, there is definitely no "shine" anymore.

What is considered de-lamination?
 
no

Delamination occurs when water, directed under pressure....peals the gel-coat and a coupla layers of fibre glass off the hull. It's famous for happening under the "shoes" on an older rxp, but...has been known to happen to others with an injured/damaged hull.

In this photo, what are we looking at? I see at least one layer of resined glass has peeled off but not knowing what that substrate is there could be at least two reasons. Obviously the adhesion was not strong enough to keep the glass layer stabilized, so I'm guessing that's foam core I'm looking at.

Similar to the foam core found in a surfboard.

Looks to me like there is a layer or 2 of fiberglass left.

At speed, all of the water on the bottom of the hull takes a bunch of pressure. Once something like that starts, there is literally no stopping it.

I was trying to think of an analogy.

It would be like sticking your hand in the water at 50 mph. That is what is hitting your hull continuously.

Now, put a bandaid on the end of your finger and do it again. What are the odds the bandaid stays on?

I would use marine -tex instead of JB weld.
Buy it in a color matching your hull and you won't see the repair.
 
I wouldn't touch that ski with anything but the correct repair. It's killing me all the half baked repairs on such a new ski. Blow the $480 and end your friendship. It will be cheaper in the long run.

Not sure what that $480 brings, I'd want more than that to "fix it right" I think.
 
I ended up JB Welding it for now - took it out today and the weld held up great.

I will likely have it completely repaired at the end of the season - I beach my ski all the time, so scuffs to the gelcoat are inevitable. The gouges should be OK with the JB Weld from now to the end of the season.

This the the service shop that quoted me $480.
